An imaging device includes: an imager that is provided in a device body; a shutter that is provided in the device body, includes a support member and a shutter member; an actuator that is provided in the device body and moves the imager in a direction orthogonal to an optical axis to correct an amount of camera shake; and a plurality of elastic members that are disposed on at least one side and the other side of an imaginary straight line passing through a center of gravity of the shutter and orthogonal to the optical axis in a case where the plurality of elastic members are viewed in a direction of the optical axis and are in contact with the device body and the support member.

Provided are a first magnetic drive unit including a first coil and a first magnet, and a second magnetic drive unit including a second coil and a second magnet. Also provided are a first drive lever and a second drive lever operated by the first magnetic drive unit and the second magnetic drive unit, respectively, a first opening and closing blade and a second opening and closing blade that open and close an opening by an operation of the first drive lever and the second drive lever, respectively. A first lock mechanism locks the first drive lever at a predetermined position, and a second lock mechanism that locks the second drive lever at a predetermined position, and a part of the first lock mechanism and a part of the second lock mechanism are located between the first magnetic drive unit and the second magnetic drive unit.
