PROBLEM TO BE SOLVED: To provide a vibration generator which can be made thin and small- sized even when a dead weight is attached thereto and of which the movable piece can be easily assembled. SOLUTION: A movable piece 50, which is freely oscillably supported on a stator by two coil springs, is constructed by attaching a permanent magnet 70 and a dead weight 60 to a movable piece yoke 51. In the weight 60, a receiving section 61 and a fitting section 63 are formed. The receiving section 61 has such a shape that it receives the magnet 70 and that the weight 60 is fixed to the yoke 51 by causing the magnet 70 to attract the yoke 51. The fitting section 63 determines the positions of the weight 60 to the yoke 51.
