Abstract
A camera module includes a fixed portion, a movable portion configured to be moved relative to the fixed portion in an optical axis direction, at least two position detection sensors, and a magnet disposed to oppose the at least two position detection sensors in a direction intersecting the optical axis direction. The magnet includes an N-pole and an S-pole on a surface opposing the at least two position detection sensors and a neutral zone between the N-pole and the S-pole. The at least two position detection sensors are disposed such that at least one position detection sensor opposes one of the N-pole and the S-pole and at least one other positon detection sensor opposes the neutral zone when the movable portion is moved in the optical axis direction.
