Abstract
It is an object of the invention to realize a snubber module which is small in size, and which can be easily handled, thereby miniaturizing a power conversion apparatus. In the invention, a snubber module () is configured so that twelve snubber diodes and a snubber capacitor which constitute a snubber circuit for suppressing a surge voltage are enclosed in a resin mold (), and a P-side lead wire () and an N-side lead wire () which are two capacitor external terminals that are connected respectively to two terminals of the snubber capacitor, and six diode external terminals () which are connected respectively to connecting portions where respective two of the twelve snubber diodes are connected to each other are exposed from the resin mold ().
