Abstract
The present invention provides an optical connector and an optical connection structure that can suppress the increase in optical loss due to curing shrinkage of the adhesive. [Solution] The optical connector comprises a resin ferrule having a connecting end face and a fiber hole opening to the connecting end face, a plurality of optical fibers inserted into the fiber hole, and an adhesive disposed inside the ferrule for fixing the plurality of optical fibers to the ferrule. Each of the plurality of optical fibers has a small diameter portion located inside the fiber hole and a large diameter portion with a larger diameter than the small diameter portion. The ferrule does not have an injection hole formed in a region perpendicular to the longitudinal direction of the fiber hole from the small diameter portion for injecting the adhesive.
