To provide a rotary electric machine and a non-contact power generator that have a good magnetic efficiency and little leak of magnetic flux. A rotary electric machine 1 is provided with a permanent magnet 2 that is disposed, so as to be rotatable around a first rotational axis, apart from one main surface of a moving body 5 that moves or rotates, wherein at least a portion of one side surface extending to the outer peripheral surface is disposed opposite the one main surface of the moving body. By means of a reactive force acting on the permanent magnet on the basis of an eddy current generated in a direction hindering a change in the magnetic flux from the permanent magnet on the one main surface of the moving body, the permanent magnet 2 rotates around the first rotation axis, and the surface speed of the one side surface of the permanent magnet disposed opposite the moving body is lower than the surface speed of the opposing one main surface of the moving body.
