发明名称 Lens barrel
摘要 A lens barrel (71) capable of preventing reflection of rays of light from a rectilinear motion-causing restriction member (6) on the inner surface of the lens barrel. In a photographic lens unit (1), to drive an actuator (5c) provided on a third lens unit (5), a flexible wiring board as a current carrying member (5b) is connected thereto. This flexible wiring board is disposed in a manner covering the inner surface of a rectilinear motion-causing restriction portion (6a, 6b) to prevent the same from being exposed toward the optical axis. Further, the flexible wiring board has a surface thereof toward the optical axis subjected to antireflection processing.
