摘要： A common connecting section for connection to terminals at the same potential in circuits is placed outside a mold section to allow a reduction in size of a semiconductor module 1. Since the common connecting section is a portion of a lead frame which would be placed within such a mold section in a conventional semiconductor module, the mold section can be reduced in size as compared with the conventional one, thereby reducing the amount of mold resin and the material cost.
