PROBLEM TO BE SOLVED: To prevent the drop of output, the demagnetization of a magnet, and the shortening of the life of a coil caused by temperature rise by suppressing the temperature rise caused by an eddy current accompanying the increase of the number of poles of a rotor. SOLUTION: A three-phase magnetic generator has a stator 200 of 3n(n:an optional natural number) in the number of poles where a coil 23 is wound, and a rotor 100 of 4n in the number of poles where a permanent magnet 13 is fixed. Here the flange 24a of a magnetic substance sheet member 24 where the coil 23 is wound in condition that the stack 21 of the stator 200 is caught is constituted to have a difference in level inward from the periphery 21b of the stacked core 21.
