Abstract
A power module includes a connection terminal for external connection, the connection terminal protruding from the side surface of a package, and a dummy terminal protruding from the side surface of the package and shorter than the connection terminal. The dummy terminal is processed to have a bottom surface with an inclination. In other words, the distance between a plane containing a heat dissipation surface of the package and the dummy terminal increases toward the extremity of the dummy terminal. Accordingly, when a heat dissipation fin is attached to the heat dissipation surface, the extremity of the dummy terminal is more distant from the heat dissipation fin than the rest of the dummy terminal.
