Abstract
In a capacitor, one capacitor electrode is formed on first principal face of a ceramic dielectric substrate. An area of a first capacitor electrode is smaller than an area of the first principal face. A second capacitor electrode is formed on a second principal face of the ceramic dielectric substrate, and connected to a lead electrode which is formed at the periphery of the first principal face of the ceramic dielectric substrate so as to be separated from the one capacitor electrode by a gap and to surround the first capacitor electrode. The ceramic capacitor is mounted on a semiconductor element through an insulating layer. The capacitor electrodes and lead electrode of the ceramic capacitor are connected to terminals of the semiconductor element by a wire bonding.
