1. A camera module comprising:
a stationary part comprising a magnet; and
a movable part comprising:
a first circuit board spaced apart from the stationary part;
a position sensor disposed on the first circuit board;
an image sensor disposed on the first circuit board;
a coil disposed so as to face the magnet; and
a spacer disposed between the first circuit board and the coil,
wherein the movable part is configured to move in a direction perpendicular to an optical axis direction by an interaction between the magnet and the coil,
wherein the spacer has a hole, and at least a portion of the position sensor is disposed in the hole of the spacer and overlaps the magnet in the optical-axis direction,
wherein the coil is disposed on an upper surface of the spacer, and
wherein the coil does not overlap the hole of the spacer in the direction perpendicular to the optical-axis direction.
