PURPOSE:To make a motor thinner by improving the precision of perpendicularity to the stator yoke of a bearing holder, and by enabling a coil mounting substrate to be made thinner. CONSTITUTION:A stator is composed of resin layers 11b, 11c set on base material 11a, a circuit pattern 9 with at least the partial section embedded in the resin layer 11b of the base material 11a and a stator coil 8 connected to the circuit pattern 9, and a stator yoke 7 to be integrally formed with a bearing holder 3 set on the other side of the base material 11a, and the stator coil 8 and the stator yoke 7 are embedded in the resin layers 11b, 11c, of the base material 11a, and they are arranged in parallel with each other to be integrally formed. |
