Abstract
A capacitor circuit (capacitor device) in which a plurality of capacitors (to) are connected to each other is included, one or two or more capacitors (overvoltage short-circuiting capacitors) in the capacitor circuit have a dielectric breakdown voltage made lower than that of another capacitor, and the one or two or more capacitors having the lower dielectric breakdown voltage are subjected to dielectric breakdown due to application of an overvoltage earlier than the other capacitor so that the capacitor circuit is short-circuited. As a result, the safety of the capacitor device and a device connected thereto can be enhanced.
