PROBLEM TO BE SOLVED: To provide the rotor structure of an axial gap rotating electric machine in which the holding strength of a rotor to a permanent magnet can be enhanced and generation torque as a rotating electric machine can be prevented from decreasing. SOLUTION: A plurality of substantially sectoral columnar permanent magnets 11 are inserted into a plurality of substantially sectoral holes 13 formed in the circumferential direction of a disc-like member 12. A holding member 14 is bonded axially from the outside to the disc-like member 12 located between the adjacent permanent magnets 11. A pair of shaft securing portions 15 are bonded to the inner circumferential side of the permanent magnet 11 in the disc-like member 12, and a pair of outer rings 16 are bonded to the outer circumferential side of the permanent magnet 11 in the disc-like member 12. The outer ring 16 is constituted by bonding an inner circumferential side 16a composed of a nonmagnetic body and an outer circumferential side 16b composed of a high strength member to each other.
