Abstract

In an lens holder, a lens 10 inserted in an insertion hole 2 is bonded and secured to a lens holder 1 by an adhesive agent poured in slots 4 formed in such a manner as to divide an outer wall portion 3. Since a sufficient amount of adhesive agent can be allowed to adhere to the lens, the lens can be fixed to the lens holder with sufficient strength. In addition, since the adhesive agent 20 poured in the slots 4 overflows also to the outer side of the slots of the lens holder 1, it is possible to reduce the amount of adhesive agent 20 flowing into the insertion hole 2 side, and it is possible to prevent the adhesive agent from adhering to the surface of the lens 20.
