ABSTRACT:
A capacitor module incorporating a ceramic capacitor having terminal members for reducing stress caused by thermal stress or electrostriction in the ceramic capacitor itself, and a semiconductor device using the capacitor module. The capacitor module and the semiconductor device are designed to have a reduced size and improved reliability. The semiconductor device has a power converter circuit constituted by switching devices and diodes, a P-polarity conductor and an N-polarity conductor for supplying electric power to the power converter circuit, a ceramic capacitor having two external electrodes, flexible terminal members connected to the external electrodes, a heat radiation plate provided at the bottom of a case, an insulating resin with which the power converter circuit is covered, a P-polarity connection conductor for connection between the terminal member on one side of the ceramic capacitor and the P-polarity conductor, an N-polarity connection conductor for connection between the terminal member on the other side of the ceramic capacitor and the N-polarity conductor, and a molded wiring plate on which a major surface of the ceramic capacitor is supported.
