Abstract
A ceramic body mainly based on BaTiO3-based crystalline particles in which a part of Ba is substituted with at least one rare earth element and at least one alkaline earth metal element. The ceramic body contains from 1.0 to 8.0% by mass of Ba6Ti17O40 crystalline particles. The BaTiO3-based crystal particles have a substituted amount of one mol of the Ba with the alkaline earth metal element of 0.01 to 0.10 mol.
