Abstract
An image stabilization apparatus is disclosed which can provide enhanced accuracy of image stabilization. The apparatus includes a movable member movable relative to a fixed member of the apparatus, plural flexible members which movably support the movable member at least in a direction orthogonal to the optical axis, a portion of each of the flexible members on one end side in a direction along the optical axis being fixed to the fixed member, a portion of each of the flexible members on the other end side being fixed to the movable member, and an actuator which drives the movable member. The flexural rigidity of at least one of the plural flexible members in the direction orthogonal to the optical axis is different from that of the other at least one flexible member in that direction so as to suppress rotation of the movable member driven by the actuator.
