ABSTRACT:
To connect N lenses to construct a lens unit for an imaging-device in series, (n−1)-th (where 2≦n (integer)≦N) lens having an outer periphery rim region which extends with a certain thickness from an outer periphery edge end portion of the lens region directing to the side of the adjacent nth lens and the outer periphery rim region which has a circular-arc tapered surface inclined with respect to an optical axis on a outer part of the lens region, and the nth lens having a bulgy-protrusion-shaped portion with head-top portion milled to be round along an outer part of the lens region on a surface of an outer periphery rim region opposed to the (n−1)-th lens are arranged, and lens position adjustment is made by putting the bulgy protrusion-shaped portion to the circular-arc tapered surface to perform point contact.
