Optical element drive device and camera module

An optical element drive device comprising:

• a support;
• an optical element holder provided with an opening capable of disposing therein an optical element and configured to move in a predetermined direction along a predetermined axis relative to the support;
• a driver including a shape-memory alloy wire to move the optical element holder in the predetermined direction;
• and
• an intermediate member provided between the optical element holder and the support, wherein
• the intermediate member is movable relative to the support and movable relative to the optical element holder,
• the shape-memory alloy wire includes a first wire provided between the support and the intermediate member, and a second wire provided between the intermediate member and the optical element holder,
• the first wire has one end supported by the support at a higher position than another end supported by the intermediate member,
• the second wire has one end supported by the intermediate member at a higher position than another end supported by the optical element holder, and
• the optical element holder moves in the predetermined direction by suppressing rotation about the predetermined axis by generating contraction of the first wire and contraction of the second wire upon applying a current to the first wire and the second wire.
