A heat sink of a drive apparatus includes a heat receiving surface located in a rising direction from an end surface wall of a motor case formed in an axial direction of the motor case. A power module includes a mold part and is arranged along the heat receiving surface of the heat sink. Motor leads are taken out from the motor case and electrically connected to the power module and winding wires. The drive apparatus has the motor case, a control circuit substrate, the heat sink, the power module and a power circuit substrate arranged in this order in the axial direction. The motor leads are connected to the power module at an opposite side of the motor case relative to the mold part in the axial direction.
