PROBLEM TO BE SOLVED: To realize the improvement of a power generating efficiency by suppressing the temperature rise of a power generating coil and to improve the lifetime and the reliability of the power generating coil. SOLUTION: A magnet generator includes a flywheel 3 having a cylindrical part 4 and rotating around a rotating axis A-A, a plurality of magnets 7 provided on the inner peripheral surface of this flywheel 3 and rotating together with the flywheel 3, a stator core 10 having a plurality of tees 12 projecting to a radial outside and opposed to the magnets 7, and the power generating coil 11 provided by winding a conductor on the tees 12. The stator core 10 has a laminated core 15 obtained by laminating a plurality of magnetic thin steel sheets, and a pair of end plates 16, 17 disposed to sandwich both the side faces of this laminated core 15, and at least one of the pair of the end plates 16, 17 is constituted by an aluminum having higher heat sink nature than the magnetic thin steel sheet.
