A vibration motor and a tactile device are provided. The vibration motor has: a stationary portion; a movable portion having a magnet and capable of vibrating with respect to the stationary portion along a central axis extending in an up-down direction; and an elastic member. The stationary portion has: a housing, disposed radially outside from the movable portion and having a cylindrical shape extending along the central axis; a top surface portion, disposed above the movable portion, fixed to the housing, and extended in a direction intersecting with the central axis; and a coil, capable of applying a driving force to the movable portion. The elastic member is disposed below the top surface portion and above the movable portion. The elastic member is fixed to the top surface portion and the movable portion and supports the movable portion so that the movable portion can vibrate along the central axis.
