Abstract: The present invention relates to a structure of a vibration operated generator which makes it possible to generate electricity by using vibration or swinging to cause electromagnetic induction. The present invention comprises a combination of a guide with a concave surface including a non-magnetic material, a permanent magnet being placed on the concave surface of the guide such that the magnet freely rolls over this concave surface, and electromagnetic induction coils being disposed in positions that cut across the magnetic flux generated by the permanent magnet.
