PROCESS FOR PRODUCING STACKED CERAMIC ELECTRONIC COMPONENT AND COMPOSITE LAMINATE

WIPO Patent Application WO/2006/043350

A1

This invention provides a stacked ceramic electronic component which can solve a problem that, when a stacked ceramic electronic component with a built-in inductor element, such as a multilayer ceramic substrate, is produced, the incorporation of an unsintered core to be provided in the inductor element causes diffusion of a material and does not sometimes provide inherent properties. In a composite laminate (56) which provides a contemplated multilayer ceramic substrate upon firing, a core (68) formed of a magnetic ceramic sinter is incorporated. In order to reduce the difference in shrinkage behavior during firing between this core (68) and an unsintered ceramic layer (57a to 63a), shrinkage suppression layers (71 and 72)containing an inorganic material powder which is not substantially sintered at the sintering temperature of the unsintered ceramic layer (57a to 63a) is provided in a composite laminate (56).
