A voice coil motor, comprising:
- a mover including a bobbin equipped with a lens and a coil block secured to an outer circumference of the bobbin;
- a stator including a magnet that is disposed in such a way as to face the coil block;
- elastic members coupled to a lower end of the bobbin and connected to both ends of the coil block;
- a base supporting the elastic members and the stator;
- and
- a cover can covering the mover, the stator and the base, with an opening being formed in the cover can to expose the lens therethrough,
- wherein each of the elastic members comprises a terminal portion that extends between the cover can and a side surface of the base, the terminal portion including a short-circuit prevention portion so as to prevent a short-circuit between the terminal portion and the cover can, and
- wherein the short-circuit prevention portion is inclined, in a direction from the upper surface of the base to a lower surface of the base that is opposite to the upper surface thereof, to approach the side surface of the base and to be spaced apart from an inner surface of the cover can.
