A shutter device includes shutter blades, a motor which drives the shutter blades, diaphragm blades which are driven by the motor to perform opening and closing operations, and a transmission mechanism which transmits a driving force of the motor to the shutter blades and the diaphragm blades. In the shutter device, the transmission mechanism transmits the driving force of the motor to the shutter blades and the diaphragm blades in such a manner that driving of the shutter blades by the motor and driving of the diaphragm blades by the motor are made sequential.
