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.

摘要： PROBLEM TO BE SOLVED: To further improve the reliability of a laminated electronic component. SOLUTION: An upper layer of an LC composite component 10 is an inductor 12, which is formed by laminating a magnetic substance of a Ni-Cu-Zn ferrite, containing NiO. A lower layer of the LC composite component 10 is a capacitor 14, which is formed by laminating a dielectric of TiO2 ceramic containing NiO. An intermediate layer 16 is interposed therebetween, which is made up of a nonmagnetic substance of Cu-Zn ferrite which does not contain NiO. The materials are selected, so as to have a difference of 15 mol% or less between a NiO content of Ni-Cu-Zn ferrite, which constitutes the inductor 12, and a NiO content of TiO2 ceramic, which constitutes the capacitor 14.

摘要： PROBLEM TO BE SOLVED: To provide a manufacturing method for a laminating electronic component wherein, when a laminated electronic component is manufactured by a print process comprising an insulator pattern with a through-hole, position accuracy of the through-hole is assured, while blurring is avoided and at the some time leveling is assured. SOLUTION: An insulator layer comprising at least a through-hole is divided into first patterns 11a-11c containing through-holes 3a-3f and second patterns 12a-12c which do not contain through-holes. When the second patterns 12a-12c are printed, a squeegee is moved faster than when the first patterns 11a-11c are printed for more flexible printing. Alternatively, such insulator paste of viscosity lower than the first pattern is used for the second pattern.
