Abstract: A vibration motor includes a stator and a vibrator that is capable of vibrating in a first direction. The stator includes a coil and a housing. The coil opposes the vibrator in a second direction perpendicular to the first direction. The housing accommodates the coil and the vibrator. The vibrator includes a mass body, a magnet, and a sliding portion. The mass body extends in the first direction. The magnet is fixed to the mass body and opposes the coil in the second direction. The sliding portion is located on an end surface of the mass body in a direction intersecting the first direction, and slides on an inner side surface of the housing when coming into contact with the inner side surface of the housing during vibration of the vibrator.
