PROBLEM TO BE SOLVED: To enhance torque generation efficiency corresponding to the number of magnetic poles to be combined while thinning each member by enabling drive circuit components to be incorporated to be operated in a same way as a standard DC motor. SOLUTION: The axial gap type brush-less motor includes a shaft support part disposed in the center of a yoke bracket 1 comprising magnetic plates, three detent torque generation parts 1b externally disposed in a radius direction, three air-core armature coils 5 wired in a single-phase fixed on a stator base attached to the yoke bracket, a drive circuit member D disposed so as not to overlap with the coil in plan view, a stator ST wherein a power supply terminal part inputting to the drive circuit member is integrally provided with the stator base in a radius direction, an axial gap type magnet 4 wherein a rotor R has four magnet poles, and a rotor yoke retaining the magnet, wherein the rotor R is rotatably fitted to the shaft and is accommodated in a housing H comprising a case 9 and the bracket 1.
