Abstract
A conductive thin-film thinner than the undersurface electrode is provided outside the undersurface electrode on the undersurface of the ceramic substrate and connected to the undersurface electrode. A length from an outer circumferential part of the undersurface electrode to an outer circumferential pert of the ceramic substrate is equal to a length from an outer circumferential part of the top surface electrode to an outer circumferential part of the ceramic substrate. A thickness of the conductive thin-film is half or less than a thickness of the ceramic substrate.
