A reflective member driving device including a housing; a holder which is disposed within the housing; a reflective member which is disposed in the holder; a moving plate which is disposed between the housing and the holder; a driving magnet and a sensing magnet which are disposed in the holder; a coil which electromagnetically interacts with the driving magnet; and a first sensor which senses the sensing magnet. The driving magnet includes a first magnet which tilts the reflective member about a first axis and a second magnet which tilts the reflective member about a second axis perpendicular to the first axis. The sensing magnet is disposed at a location where the sensing magnet does not electromagnetically interact with the coil.
