ABSTRACT:
In a composite device of the laminate type having a laminate structure of a composite ceramic layer and a dielectric ceramic layer, the composite ceramic layer including a layer portion having the same composition as the dielectric ceramic layer and a plurality of particle portions formed on the surface of the layer portion. The particle portions are made from magnetic ceramic material. This prevents the ceramic layers of the device from cracking and separating when fired.
