Abstract
Provided is an optical coupling structure including an optical semiconductor element including a light receiving/emitting portion, an optical transmission path having an optical axis that intersects the optical axis of the optical semiconductor element at a predetermined angle, and an optical coupling portion configured to convert the optical path between the optical semiconductor element and the optical transmission path and optically couple them. The optical coupling portion is made of a resin that is transparent with respect to a transmitted light, the resin adhering to both at least a portion of the light receiving/emitting portion and at least a portion of the end portion of the optical transmission path, and the optical semiconductor element and the optical transmission path are bonded to each other with the resin itself that constitutes the optical coupling portion.
