1. A camera module, comprising:
a lens module including a plurality of lenses disposed along an optical axis;
a housing accommodating the lens module; and
a reflection module disposed in front of the lens module, and including a reflective member configured to change an optical path, and a holder in which the reflective member is mounted;
a guide member disposed between the housing and the reflection module,
wherein the reflection module is rotatably disposed on a first axis and a second axis perpendicular to the optical axis,
wherein a first position sensor configured to sense a position change of the reflection module with respect to the first axis is disposed in the housing,
wherein a second position sensor configured to sense a position change of the reflection module with respect to the second axis is disposed in the housing,
wherein a sensitivity of the first position sensor is different from a sensitivity of the second position sensor, and
wherein side walls of the holder protrude along the optical axis to cover the guide member.
