Abstract:
1. A semiconductor module comprising: a semiconductor chip for switching energization of a winding related to drive of a motor; a wiring board that is mounted with the semiconductor chip and that has an energization route routed through the semiconductor chip; a mold section that is formed from a resin in the shape of a plate such that the semiconductor chip and the wiring board are embedded in the mold section; a winding connection terminal extending from the wiring board to an outside of the mold section, the winding connection terminal being connected with the winding; a control terminal extending from the wiring board to the outside of the mold section, the control terminal being connected with a control board that controls the energization of the winding; and a plurality of lands provided on a side of the wiring board opposite to the semiconductor chip, the lands having radiation surfaces exposed from the mold section and being capable of dissipating a heat, which is generated by the semiconductor chip, by establishing surface-to-surface contact between the radiation surfaces and a radiation member, wherein the lands constitute a land row, in which the radiation surfaces are arranged on the same plane and on a straight line.
