COMPOSITE CERAMIC MULTILAYER SUBSTRATE, HEAT GENERATING ELEMENT-MOUNTING MODULE, AND METHOD OF PRODUCING COMPOSITE CERAMIC MULTILAYER SUBSTRATE
A composite ceramic multilayer substrate includes a glass ceramic insulating layer including a wiring layer and a highly thermally conductive ceramic insulating layer made of a ceramic material having a higher thermal conductivity than the glass ceramic insulating layer. The glass ceramic insulating layer is provided on one main surface of the highly thermally conductive ceramic insulating layer or both main surfaces of the highly thermally conductive ceramic insulating layer directly and/or with a wiring layer interposed therebetween. When viewed in a direction perpendicular or substantially perpendicular to a main surface of the composite ceramic multilayer substrate, the composite ceramic multilayer substrate includes at least one heat generating element-mounting portion surrounded by the glass ceramic insulating layer and at which a heat generating element-mounting wiring line provide on the main surface of the highly thermally conductive ceramic insulating layer is exposed.
