Abstract
A semiconductor module includes a ceramic board, a circuit pattern metal plate on a principal surface of the ceramic board, and an external connection terminal including a bonding portion and a conductive portion. The metal plate includes a bonding area at a first surface thereof, and a stress relaxation portion disposed within the bonding area. The bonding portion has a bonding surface, and an edge that is located at a position overlapping an area in which the stress relaxation portion is disposed in a plan view. A solder is disposed between the bonding surface and the bonding area, to bond the external connection terminal to the circuit pattern metal plate.
