ADHESIVE STRUCTURE OF OPTICAL COMPONENT, AND MANUFACTURING METHOD THEREOF

PROBLEM TO BE SOLVED: To provide an adhesive structure of an optical component which is hardly affected by expansion or contraction of an adhesive due to an ambient environment, can suppress a deterioration in performance, and can sufficiently secure adhesion strength.SOLUTION: In the structure, a groove part having a wall surface at the same position as a lateral face of an end of a protrusion part for fixing is formed on a mounting surface of an adhesion part of an optical component with the protrusion part for fixing of the optical component mounted thereon, or a groove part is formed in front of the end of the protrusion part for fixing, and an adhesive supplied from an upper part of the protrusion part for fixing wets a lateral face of the end of the protrusion part for fixing to flow into the groove of the adhesion part of the optical component, and is cured after continuously wetting the wall surface of the groove part. The adhesive envelops the protrusion part for fixing and the lateral face of the groove part of the adhesion part of the optical component.
