In this lens barrel, for an optical member moving along the optical axis, the flexible printed substrate is bent and mounted around the optical axis. Thereby, since the bending radius of the flexible printed circuit board is increased, the elasticity of the flexible printed circuit board can be reduced. Therefore, the impedance force generated by the flexible printed circuit board can be surely reduced. The optical member can be smoothly moved along the optical axis. Here, in the lens barrel, the flexible printed substrate is adapted to be bent along the periphery of the optical portion 2 member. With such a configuration, the bending radius of the flexible printed circuit board can be made larger, and a limited storage space can be effectively utilized. Further, the photographing apparatus relating to the present invention includes the above-described lens barrel and an imaging element that detects light imaged by the lens. According to this image pickup apparatus, since the above-described lens barrel is provided, the resistance of the flexible printed circuit board can be reliably reduced, and the optical portion 4 M358306 can be moved by 1 (9802.13) along the optical axis.
