A drive device and a lens unit include a base member; a driven member disposed at a prescribed distance from the base member and having a flat plane; a support member coupling the base member and the driven member and supporting the driven member so as to substantially maintain a prescribed distance between the base member and the driven member from start to end of movement of the driven member; and a driving member driving the driven member so as to move the flat plane in parallel from start to end of movement. The driving member causes a linear shape-memory alloy wire to expand and contract, thereby moving the driven member.
