<p>Disclosed is a vibration type electromagnetic generator provided with a first pipe (2) which is made of a nonmagnetic material and is hollow, and both end portions of which are closed, a magneto coil (9) which is wound around the first pipe (2) and is provided with solenoid coils (4a-4c), and a movable magnet (3) which is disposed in the first pipe (2) and is capable of being moved along a winding shaft direction of the magneto coil (9). The movable magnet (3) is provided with a plurality of magnets and a magnet fixation unit which is made of a nonmagnetic body and fixes the plurality of magnets, the same poles of which are opposed to each other. Out of the plurality of solenoid coils, the coil length of at least one solenoid coil is set to a length that is equal to or longer than the magnet length of the magnet.</p> |
