To provide a highly efficient and compact axial gap type dynamo-electric machine simultaneously meeting miniaturization of axial gap type dynamo-electric machines and high strength of core retention.
In the axial gap type dynamo-electric machine 101, a stator 2 is sandwiched with a prescribed gap for oppositely disposing rotors 3 along an axial direction of a rotor shaft 1. The stator 2 includes: a plurality of rod-like stator cores 22 disposed along a circumferential direction with the axis of the rotor shaft 1 as the center axis while directing its axial direction toward the axial direction of the rotor shaft 1; a disk-like core retention member 21 including a plurality of holes or grooves in nearly the same shape as the sectional shape of the stator core 22 along a circumferential direction with the axis of the rotor shaft 1 as the center axis; and a coil 23 wound around the stator core 21. The stator core 22 is inserted into the holes or grooves of the core retention member 21, and is fixed and held near the center in the axial direction.
