摘要： PURPOSE:To prevent a crosstalk by forming between inductors a short ring that crosses a magnetic flux that passes between the inductors. CONSTITUTION:In a complex inductor 1, a conductor 11a formed of conductor paste, the same material of a conductor for forming a coil 3, is applied between inductors 2a and 2b so that its both ends may be exposed to outside of a laminate at the same time with application of the conductor for forming a coil 3, in the lamination process. Nextly, the conductor for forming a coil and an insulator are laminated and the laminate thus obtained is bonded and sintered into one body. Then, a closed-loop conductor 11b formed of conductor paste is so formed as to surround the external part of the laminate between the inductors 2a and 2b in the shape of a ring, being connected to both ends of the built-in conductor 11a, and is sintered into one body with the laminate. Thus, a short ring 11 is formed. By this, a magnetic flux going to an adjacent inductor is consumed as current by the short ring and thereby a crosstalk can be prevented. At the same time, the size of the component can be reduced and the manufacturing processes can be simplified.

摘要： PURPOSE:To provide a stacked noise absorbing element composite of such structure that the crosstalk between coil conductors can be prevented, that the downsizing can be materialized, and that the manufacture is easy. CONSTITUTION:In a stacked noise absorbing composite, which has built in a plurality of coils corresponding to a plurality of channels by stacking magnetic layers and coil conductor layer alternately, a plate-shaped earth conductor 13 is made between each coil conductor 11 and the next by piling up conductor layers in the direction of the stacking of coil conductors 11. A zigzag earth conductor may be used in the same layer as the coil conductor, in place of the plate-shaped earth conductor 13. The magnetic fluxes going to the adjacent coil conductors out of the magnetic fluxes generated by applying currents to the coil conductor are consumed as the currents flowing to the earth conductor, so it turns out that they are hard to reach the adjacent coil conductors, and also by the intervention of the earth conductor, the electrostatic coupling between adjacent coil conductors become weak, so this does not cause crosstalk.

摘要： PURPOSE:To provide a laminated electronic part having a structure capable of preventing cross talk between internal electrodes for signals or the deterioration of characteristics and being miniatuarized in the laminated electronic part such as a laminated through-type ceramic capacitor, etc., having internal electrodes for signals with a plurality of channels. CONSTITUTION:Grounding internal electrodes 6 are arranged parallel adjacent to internal electrodes 4, 5 for signals. Also, grounding internal electrodes of one layer or more are arranged continuously or discontinuously even in a layer different from the internal electrodes between the internal electrodes 4, 5 for signals. Also, the internal electrodes for signals with a plurality of channels are respectively arranged in a different layer.
