An image stabilizer includes a support member, a movable member holding a correcting member and rotatable relative to the support member around a first rotating axis, which intersects with an optical axis, or a second rotating axis, which intersects with both the optical axis and the first rotating axis, and a restricting member which rotatably holds the movable member around the first rotating axis and restricts rotation of the movable member around the second rotating axis. The support member rotatably holds the restricting member around the second rotating axis along with the movable member and restricts rotation of the restricting member relative to the support member around the first rotating axis.
