Abstract
According to one embodiment, there is provided an axial gap type permanent magnet electric rotating apparatus including a first and second rotor. All a magnetic-pole directions of a permanent magnets of the first and second rotor are the same. A portion between two permanent magnets along a circumferential direction of each rotor is made of a magnetic material having substantially the same size as that of the permanent magnet such that axial-direction surfaces are the same between the permanent magnets on two sides in the circumferential direction. Between the first rotor and the second rotor, a magnetic flux flows along an axial direction while making a loop and passes through an armature.
