Composite devices of laminate type and processes

摘要

In a composite device of the laminate type having a laminate structure of a composite ceramic layer 3 and a dielectric ceramic layer 2, the composite ceramic layer 3 comprises a layer portion 31 having the same composition as the dielectric ceramic layer 2 and a plurality of strip portions 32 formed on the surface of the layer portion 31. The strip portions 32 are made from magnetic ceramic material. This prevents the ceramic layers of the device from cracking and separating when fired.
