ABSTRACT:
Provided is an optical apparatus including: two magnets which are constituent components of drive member for moving a lens holder (21); three balls (25); and two bias members (23) for applying biases such that hook portions disposed in one and the other ends of each of the two bias members are engaged with a base member (28) and the lens holder, respectively, and the three balls are held between the base member and the lens holder. Two magnets (22A and22B), the three balls, and the two bias members are arranged so that a center of gravity within a plane of the base member, a lens, and the two magnets is positioned in a triangle formed by the three balls, and a line segment within a plane formed by the two bias members steps over two sides of the triangle.
