PURPOSE:To improve the assembling efficiency without enlarging a lens barrel, and prevent an non-required load from being given to a lens by designing the arrangement of a flexible printed board. CONSTITUTION:In the lens barrel having front and rear lens groups L2, L3 and L4 mutually arranged on the same axis, front and rear electric parts 21, 32, 42a, and 53 integrated to the front and rear lens group L2, L3, and L4, respectively, and front and rear flexible printed boards 63, 65 having conductive patterns on the surfaces to electrically connect each electric part to an electric part provided on the barrel outer part, at least one lens group being constituted in such a manner as to be capable of driving in the optical axial direction, the front and rear flexible printed boards 63, 64 are arranged in the lens barrel internal space in the superposed state so that the mutual reverse faces are opposed to each other. |
