A shutter device mounted in a compact device such as a camera or mobile phone is provided. The shutter device includes, a base which forms a light permeation hole through which a film or a charge coupled device (CCD) is exposed to a light; a first and second electromagnets which are mounted to opposite sides of the base; a driving arm in which one end is rotatably assembled with a side of the base between the first electromagnet and the second electromagnet; a first and second shutters which open or close the light permeation hole while concurrently rotating about a part of the base in association with the rotation of the driving arm; and a magnetic which is mounted to an end of the driving arm, and rotates the driving arm in a clockwise or counter clockwise direction while moving by the magnetic force between the first electromagnet and the second electromagnet along a direction of an electric current applied to the first and second electromagnets.
