A motor case part (30) having a stator (36) and a gear case part (50) having a reduction mechanism (SD) are integrally formed of the same material. In this manner, heat is directly dissipated from the motor case part (30) to the outside without the gear case part (30). Therefore, a brushless wiper motor (20) can be improved in heat radiation performance so as to enhance strength in high temperature can be realized. By manufacturing the motor case part (30) and the gear case part (50) from aluminum, while sufficient radiation performance is secured, a thickness thereof is made thin and lack in rigidity can be overcome. Furthermore, It is unnecessary to manufacture the motor case part (30) and the gear case part (50) individually and it is also unnecessary to perform pressing to a steel plate like the conventional art. Therefore, workability of the motor case part (30) and the gear case part (50) can be improved.
