A shutter device includes: a first light shielding member disposed at a position further frontward relative to an image-capturing surface of an image sensor, which blocks a light flux from a subject by traveling along a predetermined direction of travel; and a second light shielding member disposed at a position further frontward relative to the image-capturing surface of the image sensor, which blocks the light flux by traveling along the direction of travel, wherein: at least either a length of a light shielding range of the first light shielding member, measured along the direction of travel, or a length of a light shielding range of the second light shielding member, measured along the direction of travel, is smaller than a length of the image-capturing surface along the direction of travel.
