Abstract
This lens barrel includes a lens-receiving surface that extends in an intersection direction intersecting the central axis; a side frame portion that is arranged further outward than the lens-receiving surface in the intersection direction and that protrudes in the direction of the central axis from the lens-receiving surface; and a plurality of caulking portions that are formed at a tip portion of the side frame portion in the protruding direction and are deformed by external pressure to caulk and fix a lens between the caulking portions and the lens-receiving surface. The lens-receiving surface is formed so as to be axisymmetrical to the central axis.
