A lens barrel (3) is provided with a local maximum outer diameter part (3e) and a maximum outer diameter part (3a), and the maximum outer diameter part (3a) is provided on a part of the area of the local maximum outer diameter part (3e) that includes the outer periphery of an imaging lens with the largest lens diameter (2m). This structure allows for high-accuracy attachment of a lens barrel and further reduction in size. |
