PROBLEM TO BE SOLVED: To provide a photographing device where the residuum of a gate does not hinder the opening/closing actuation of a shutter blade even when the residuum exists at the time of resin-molding the shutter blade. SOLUTION: By rapidly pressing the actuation part of the shutter blade at the time of release, the shutter blade is turned back and force, and its opening/closing part opens/closes an aperture part formed on a shutter base plate. Then, the shutter blade is provided with a connection part connecting the actuation part and the opening/closing part in crank shape, and the gate for resin-molding is arranged at the connection part.
