To provide a lens barrel made reliable, and made small in size and thin in thickness.

The lens barrel 10 has a 1st group frame 31 and a fixed frame 32, and incorporates a prism to refract subject luminous flux from an incident optical axis to an optical axis being in a perpendicular direction in the 1st group frame. A lens group capable of moving forward and backward, a shutter unit and a CCD or the like are arranged in the frame 32, and a solenoid for driving a shutter is arranged on the left side of the frame 31 and a step motor for driving a lens group is arranged on the left side wall part 32k of the frame 32. PRs 58 and 59 for detecting the position of a lens group are positioned on a front side wall part 32j and mounted on an FPC for connection 86, and the motor terminals 53d and 54d of the step motor are inserted through the insertion holes 32m and 32n of the wall part 32k to the outside and connected to the FPC 86. By arranging the solenoid and the step motor on the left side of the frame member, the lens barrel is thinned.
