シャッターの遮光構造。A printed coil is formed on the surface of the shutter blade by metal foil adhesion etching or metal vapor deposition, and when the coil is energized, electromagnetic force is generated by the action with a permanent magnet, or by a combination of the electromagnetic force and the action of a spring. In an electromagnetic drive shutter in which a shutter blade is operated between a closed position that covers a shutter opening and an open position that opens the shutter opening, an area portion of the shutter blade that covers the shutter opening is used to form the printed coil. A light-shielding structure for an electromagnetic shutter, characterized in that a light-shielding surface made of the same material as the printed coil is formed by simultaneous processing with the printed coil.
