In a lens actuator on which a first lens and a second lens are mounted, since the first lens and the second lens are disposed side by side, a problem is involved such that the lens actuator is bulky. The present invention provides a lens actuator comprising a first lens and a second lens having different optical paths, disposed between a light emitting element and an object lens, a holder for holding the first lens and second lens such that the optical axes of the first lens and second lens are parallel to each other, and a driving mechanism for driving the first lens and second lens each in the optical axis directions, wherein the first lens and second lens have respective outer periphery parts respectively outside the effective diameter, and the outer periphery parts of the first lens and the second lens are disposed to be partially overlapped with each other when viewed from the first lens and second lens optical axis direction.
