<p>A lens barrel is provided with a lens holder, and an imaging lens composed of a plurality of three or more lenses inserted and fitted into the lens holder. The lens barrel is configured in such a manner that resin spacers having elasticity in the optical axis direction are disposed between the lenses that affect the curvature of field, and a pressing force is applied between the lenses that affect the curvature of field, thereby deforming the resin spacers so as to be fixed in place. Thus, a pressing force is applied between the lenses, which easily affect the curvature of field, thereby elastically deforming the resin spacers in the optical axis direction, enabling the space between the lenses to be adjusted. As a result, the curvature of field can be corrected, and a reduction in resolving power can be prevented.</p> |
