There are provided an axial gap motor which can reduce the number of manufacturing steps due to permanent magnets not having to be fixed by an adhesive and which can prevent permanent magnets from being displaced or loosened so that the permanent magnets can be positioned within a rotor frame in an ensured fashion and a manufacturing method for manufacturing a rotor for the motor. A rotor 11 of an axial gap motor 10 comprises a plurality of main magnet portions 41 which are magnetized in the direction of the rotational axis and which are disposed at predetermined intervals in a circumferential direction, a plurality of yoke portions 42 which are formed by a lamination member 71 into which a tape-like sheet of electromagnetic steel 60 is wound and which are disposed on either side of the plurality of main magnet portions 41 with respect to the direction of the rotational axis, and a rotor frame 30 having a plurality of ribs 31 which are disposed individually between the main magnet portions 41 which lie adjacent to each other in the circumferential direction and which extend in a radial direction, and an inner cylindrical portion 32 and an outer cylindrical portion 33 which are provided at inside diameter sides and outside diameter sides, respectively, of the plurality of ribs 31 and made of a die casting alloy. The main magnet portions 41 each have a groove 41a at an inner circumferential side thereof for preventing the displacement of the position of the main magnet portion 41.
