内容: | This invention provides a ceramic multilayer substrate that can suppress separation or disconnection of an internal conductor in such a state that an internal conductor is disposed between a ceramic layer as a substrate and a ceramic layer for a shrinkage inhibition. The ceramic multilayer substrate comprises a first ceramic layer (11), a second ceramic layer (12) stacked so as to contact with a principal plane of the first ceramic layer (11), and an internal conductor (13) provided between the first ceramic layer (11) and the second ceramic layer (12). A phosphor component layer (16a) with a concentration gradient is provided in the first ceramic layer (11) so that the concentration of phosphor decreases as the distance from the internal conductor (13) increases. |
