A shutter unit includes a base plate on which an opening is formed, at least one blade member, a driving member configured to be rotatably supported by the base plate and to drive, in imaging, the blade member from a standby position to a traveling completion position by using a biasing force of a biasing member, a braking member configured to cause the driving member to decelerate by coming into contact with the driving member, and a charging member configured to cause the driving member to operate to the standby position after causing the driving member to operate from the traveling completion position to a set position against the biasing force of the biasing member, and cause the braking member to operate from the traveling completion position to the standby position while causing the driving member to operate from the set position to the standby position.
