A heat sink (35) is fixed by insert molding to a resin-made motor cover covering a case body fixed to a motor body. A flow-in portion (61) extending along a straight line and branch portions (62) to (66) formed so as to be branched to the flow-in portion (61) are formed in the heat sink (35), a tip portion of a power-feeding terminal (58) is disposed at the branch portion (62), and the tip portion of the power-feeding terminal (58) is disposed at the branch portion (63). In addition, when a molding resin is cast in the flow-in portion (61) and the branch portions (62) to (66) during the insert molding, these power-feeding terminals (58) and (59) are fixed to the branch portions (62) and (63) and terminal parts (58b) and (59b) are positioned by the branch portions (62) and (63).
