A camera shutter comprising a shutter driving means which has permanent magnets on both ends of a swingably journaled swinging lever and drives a shutter blade by conduction of electricity to a magnet coil wound around an iron core that is fixed so as to face the permanent magnets, thereby performing efficient motion. In one embodiment, a first sheet is formed into a first leg, a second sheet is formed into a second leg, a third sheet is formed into a stem, and the two legs are attached to the stem. An intercepting trench is formed on the gate line to cut off the doped layer and the active layer on the gate line.
