Abstract
A bonding structure of optical members has a first optical member, a second optical member, a first support member supporting the first optical member, and a second support member supporting the second optical member. The first support member is bonded to the second support member. The first support member and the second support member are bonded with each other via a hardened acrylic resin adhesive under a condition such that an optical axis of the first optical member and an optical axis of the second optical member are optically aligned with each other with an accuracy of within 1 &mgr;m. A viscosity of the acrylic resin adhesive before hardening is larger than 500 cP and lower than 5000 cP.
