A scanner (6) includes: an optical fiber (14) that guides light from a light source； a drive unit (16) including at least one actuator (21) that, when a voltage is applied thereto, displaces an exit end (15) of the optical fiber (14) in a direction intersecting an optical axis (S)； a support portion (17) that is provided on a basal end side from the drive unit (16) and that is spaced away from the drive unit (16) to support the optical fiber (14)； and a correction portion (18) that performs correction so as to bring the center of gravity of the drive unit (16) and a combined center of gravity of the optical fiber (14), the drive unit (16), and the support portion (17) close to each other on a cross-section of the drive unit (16).
