ABSTRACT:
To provide a digital camera which is thinner than conventional when a lens barrel is collapsed, and is improved in suppression of degradation of image quality due to dust or the like introduced into the lens barrel. A lens barrel has: an optical-member advancement/retraction mechanism that retracts any of plural optical members from an optical axis for picture taking when the lens barrel is collapsed, and advances the optical member, which is retracted when the lens barrel is collapsed, onto the optical axis for picture taking when the lens barrel is extended; and a cleaning member that cleans at least either of the optical member or one, which is adjacent to the optical member, of the plural optical members and a solid-state image pickup section as a result of retracting or advancing the optical member by the optical-member retraction/advancement mechanism.
