PROBLEM TO BE SOLVED: To provide an optical apparatus capable of reducing influence of thermal expansion by irradiation of hardening light when a resin component is bonded by a photo-curing type adhesive material.SOLUTION: With an adhesive fixing structure, a first member and a second member holding a lens are fixed using a photo-curing type adhesive material in a lens barrel composed of a plurality of lens groups. After adjusting the first and the second members, the photo-curing type adhesive material is applied and fixed by irradiating the same with hardening light. The adhesive fixing structure includes a wall section shielding between an adjustment section configured to push the first or the second member during adjustment and an application section where the photo-curing type adhesive material is applied.SELECTED DRAWING: Figure 1 |
