ABSTRACT:
There is provided an axial gap type rotating electric machine which is small-sized and achieves a high motor efficiency as a drive source having a high torque using a strong magnet by reducing energy loss by an induced current. An axial gap type rotating electric machine having a yoke on a side of a rotor in a circular plate shape fixed to a rotating shaft, a yoke23on a side of a stator in a circular plate shape opposed to the yoke on the side of the rotor, a magnet fixed to a side of an opposed face of either one of the yokes on the side of the rotor or the side of the stator, a plurality of teeth24arranged on a side of an opposed face of other yoke on the side of the rotor or the side of the stator radially and opposedly to the magnet, and a coil25wound around each of the plurality of teeth, in which the yoke23has a fixing portion including a hole or a recess for inserting a portion Of the teeth to fix, and in which a resistance portion against an induced current (slit36)is provided at a surrounding of the fixing portion.
