Zusammenfassung:	A motor controller which is inexpensive and has high cooling performance by using an extrusion heat sink (1), reducing the number of parts, and reducing the man-hours of assembling is provided. In a motor controller including an extrusion heat sink (1), and a power semiconductor module (4) including a plurality of external electrode terminals which closely contact the extrusion heat sink (1), and a printed circuit board having the plurality of external electrode terminals connected thereto, die-casting frames (2) in which a pedestal (2a) for attaching a motor controller and bosses (2b) for attaching a printed circuit board are molded are provided at both ends of the extrusion heat sink (1).
