PROBLEM TO BE SOLVED: To provide a lens barrel capable of preventing or reducing wear or the like by bringing a flexible substrate into contact with the other member or the like even when the flexible substrate is moved and deformed by accompanying the movement of a movable component such as a lens holding frame. SOLUTION: The lens barrel having a lens barrel body and a wall part for partitioning the inside and outside of the lens barrel by being provided in the lens barrel includes: the flexible substrate continued through a bent part by an external flexible substrate arranged in the outside of the lens barrel body and an internal flexible substrate arranged in the inside of the lens barrel body; and a fall prevention flange formed on the internal flexible substrate. The lens barrel forms a groove extending in a thickness direction of the wall part on the end face of the wall part, sets an interval between the bent part and the fall prevention flange to substantially same as the thickness of the wall part, and positions the internal flexible substrate between the bent part and the fall prevention flange in the groove.
