ELECTRONIC COMPONENT
First Claim
1. An electronic component comprising:
- a ceramic substrate;
a laminate which is disposed on a surface of the ceramic substrate and in which an internal circuit formed from an electrode pattern is disposed in the inside of a plurality of laminated resin insulating layers;
internal electrodes electrically connected to the internal circuit and exposed at an end surfaces of the laminate; and
external electrodes disposed on the end surfaces of the laminate and electrically connected to the internal electrodes,wherein the resin insulating layers are provided with expansion relaxation portions located in the vicinity where the internal electrodes and the external electrodes are connected to each other, the expansion relaxation portions being adapted to relax the expansion on the end surface sides.

Abstract
An electronic component is configured to include a laminate disposed between first and second magnetic substrates. The laminate is formed by laminating resin insulating layers, a coil pattern, and a lead pattern. The coil pattern is connected to external electrodes disposed on end surfaces of the laminate by using internal electrodes. The electronic component further includes expansion relaxation portions disposed in the inside of the resin insulating layers and located in the vicinity of connection regions of the internal electrodes and the external electrodes. The expansion relaxation portions are formed by using a magnetic powder resin in which a ferrite powder and a resin material are mixed.
