A shutter device having two shutter plates, which shield between an IBS and a substrate, is configured such that the two shutter plates are disposed at symmetrical positions across the IBS and can perform an opening/closing operation in synchronization with a rotation of a rotation-link-member which is rotatably disposed surrounding the IBS. With the configuration, the shutter device can reduce an offset of a shield range in the opening/closing operation.
