PROBLEM TO BE SOLVED: To contrive arrangement of a shutter unit equipped with a notched surface parallel with an optical axis to an imaging device, so that strength of the guide holding part of a lens barrel substrate is secured while keeping extending amount of a rear lens group long by effectively using limited bow-shaped space between the notched surface and a cam mechanism, and to arrange a shutter flexible substrate so as to curve and get into the bow-shaped space, so that the length is secured and rolling-in is prevented, and to cover the bow-shaped space with a front lens frame, so that stray light is intercepted.;SOLUTION: The shutter 5 has constitution where the notched surface 5a parallel with the optical axis is formed on the outer periphery of a nearly disk-shaped body, and is fixed to the front lens frame 2A so that the notched surface can be nearly parallel with a diagonal of a rectangular imaging device 6, and constituted so that a lead screw 7a and a guide holding part 1a get into space surrounded by the inner wall of a cam mechanism C and the notched surface of the shutter when the front lens frame moves backward.;COPYRIGHT: (C)2009,JPO&INPIT
