In a shutter drive device for a camera, the device including: a plate having an aperture; a shutter blade provided in the plate, and for opening and closing the aperture; and an driving source provided in the plate, and for driving the shutter blade. The driving source includes: a rotor magnetized with plural magnetic poles in a circumferential direction, and rotatable about an axis thereof; a stator generating magnetic force against the rotor; and a coil provided in the stator and for exciting the stator. The rotor has an arm portion extending outwardly in a direction perpendicular to the axis of the rotor, and a pin portion engaging with the shutter blade and provided in the arm portion to stand. The rotor, the arm portion and the pin portion are disposed within a thickness of the coil in the axis direction.
