摘要： A multilayer hybrid circuit having a laminated body having at least one of a plurality of dielectric layers, dielectric magnetic layers, and conductive patterns on said dielectric layers and said magnetic layers, is produced through printing process and sintering process, and composes capacitors, inductors, and resistors. An external connection is effected by side terminals positioned on side walls of the laminated body. A coupling conductor which is perpendicular to a dielectric plane is provided for coupling elements on different planes. Said coupling conductor is a succession of essentially S-shaped conductor chips or lines with the ends connected to adjacent conductor chips on different planes. That coupling conductor functions via a through hole conductor in a prior printed circuit board, and has high operational reliability in a component which is produced through sintering process. In one embodiment, an inductor is produced by a pair of coils connected in series with each other to reduce the thickness of the laminated body while providing high inductance.

摘要： PROBLEM TO BE SOLVED: To provide a stacked inductor which is arranged so as to prevent conductive patterns of the uppermost and the lowermost layers constituting an inner coil of the inductor from having short circuit at through hole portions. SOLUTION: Insulating layers 1m, 1n having lead-out conductor patterns 2i, 2j are provided as the lowermost and the uppermost layers, respectively, for constituting the coil. The patterns 2i, 2j are formed at the positions which do not align with the through holes 3a, 3f, respectively, for connecting coil conductor patterns 2a, 2g adjacent to the patterns 2i, 2j in the stacked direction, to coil conductor patterns 2b, 2f of the subsequent layers, respectively. The patterns 2i, 2j are led out to the sides of the stacked body and connected to terminal electrodes, respectively, disposed on the sides. COPYRIGHT: (C)2003,JPO

摘要： PURPOSE:To obtain an electronic part having small eddy current loss, low loss, low heat generation, high efficiency and excellent magnetic characteristics by a method wherein, in an electronic part in which a coil is embedded in a coil-supporting body, the supporting body is composed of a plurality of magnetic parts, arranged leaving a space between them, and an insulating part. CONSTITUTION:A coil supporting member 2 is composed of a plurality of magnetic parts 21 arranged leaving an interval between them, and insulating parts 22. Each of the magnetic parts 21 constitutes the magnetic path for the magnetic flux formed by a coil current, and the insulating parts 22 are arranged in such a manner that the intervals between the magnetic parts 21 and 21 are buried. The magnetic flux phi1 formed by the coil current moves toward the direction of coil spool O1, and an eddy current Ie is going to be generated around the coil spool O1. As the insulating parts 22 are located in the direction of the above-mentioned eddy current Ie, the eddy current Ie is broken by the insulating parts 22, and no eddy current Ie is allowed to flow between the magnetic parts 21 and 21. As a result, the loss of the eddy current is small, and an electronic part of low loss, low heat generation and high efficiency can be obtained.

摘要： PURPOSE:To prevent saturation even for an increased electric current by a method wherein a laminated-coil type inductance element used in a unilateral magnetic field (magnetic field generated by an electric current only in the positive or negative direction) such as a choke coil is constituted of the following: a soft-magnetic core; a coil conductor forming a magnetic path in the magnetic core; and a permanent magnet with one part of the magnetic core is substituted. CONSTITUTION:A paste layer in which a soft-magnetic ferrite powder and a binder have been mixed and a paste in which a conductive powder of copper, silver, silver-palladium or the like has been mixed with a binder are printed alternately in a layer shape to form a laminated coil. In a halfway part of a laminate process at this time, a magnetic powder for permanent magnetic use is laminated, only in the prescribed number of layers, on an arbitrary part used as a magnetic path of a magnetic core. The magnetic powder is constituted of a paste which is composed of a barium ferrite and a plastic binder. In this manner, an inductance element is constituted of the following: a magnetic body 1 used as the magnetic core; a coil conductor 2 which is wound around it; a laminated magnet 3 arranged inside the magnetic path at the inside of the magnetic body 1.
