ABSTRACT:
In a multilayer ceramic substrate having a built-in capacitor provided in a ceramic laminate including a plurality of ceramic layers laminated to each other, the built-in capacitor being formed of a first capacitor electrode, a second capacitor electrode, and one of the dielectric glass ceramic layers, the capacitance value of the built-in capacitor is adjusted by performing laser trimming of the first capacitor electrode. The one dielectric glass ceramic layer is made of a TiO2-based dielectric glass ceramic layer in which the amount of dielectric grains including TiO2is about 10 percent to about 35 percent by volume.
