Abstract
A ceramic multilayer substrate in which cracks resulting from the difference in shrinkage caused by heat or thermal shrinkage caused by firing can be prevented effectively between an end surface electrode and a substrate main body. The substrate main body includes alternately stacked first and second ceramic layers, and including first recesses provided in end surfaces of at least two adjacent ceramic layers so as to communicate with each other, and an electroconductive end surface electrode is disposed in the first recesses in the substrate main body. The first and the second ceramic layer each have a sintering start temperature and a sintering end temperature, and at least one of the sintering start temperature and the sintering end temperature is different between the first and the second ceramic layer. The substrate main body has a second recess in at least one of the ceramic layers having the first recesses so as to communicate with the first recess and lie between other ceramic layers. In the second recess, an electroconductive protrusion connected to the end surface electrode is disposed.
