PROBLEM TO BE SOLVED: To provide dielectric porcelain enhanced in reliability at high- temperature load test and prolonged in service life. SOLUTION: This dielectric porcelain consists of crystalline particles each consisting of perovskite type multiple oxide of Ba, Ti, a rare earth element, Mg and Mn as metallic elements and grain boundary phases. The rare earth element is made to exist more extensively to the center part side of the crystalline particle compared with Mg. |
