ABSTRACT:
A power circuit section is adhered to a circuit arrangement surface on a heat radiation member to form a circuit assembly. A casing body is mounted on the heat radiation member. The casing body is provided with an opening that exposes at least the upper portion of the power circuit section. A shape retention member is disposed across the opening for interconnecting a peripheral edge of the opening to each other at a plurality of positions. A casing unit is made of a synthetic resin. The shape retention member suppresses a deformation of the casing body due to a shrinkage cavity. After cooling the casing unit, the shape retention member is removed to define a large opening, if desired.
