PROBLEM TO BE SOLVED: To provide an optical coupling structure which is manufactured at a low cost, transmits an optical signal at higher efficiency and compatible to the exchange of optical transmission lines, and to provide a method of manufacturing the optical coupling structure. SOLUTION: The optical coupling structure 5 includes: an optical semiconductor element 1 which has a light receiving/emitting part 1a and is mounted on a substrate 4; and an optical coupling part 3 made of a resin transparent to transmitting light and the end part of a fiber connector 2C, which is closely connected to the optical coupling part 3, are fitted on the light receiving part of the semiconductor element. The method of manufacturing the optical coupling structure includes: a step in which a lump of the liquid transparent resin is placed on the light receiving/emitting part 1a of the optical semiconductor 1 mounted on the substrate 4, the fiber connector 2C fitted to the fiber is plunged into the lump of the transparent resin, and the fiber connector 2C is pulled obliquely upward so that the shape of the surface of the transparent resin forms any one of recessed face parts 11, 12, 13; and a step in which the transparent resin is hardened.
