An optical fiber coupling structure for optically coupling an emission-side optical fiber and an incidence-side optical fiber includes: an emission-side base (4); and an incidence-side base (6), wherein the emission-side optical fiber is secured to the emission-side base, and an end (3C) of the emission-side optical fiber is exposed at the coupling end surface (12), wherein the incidence-side optical fiber is secured to the incidence-side base, and an end (5C) of the incidence-side optical fiber is exposed at a slope (5D) provided in said incidence side base, and wherein the coupling end surface of the emission-side base is abutted against the abutting surface (22) of the incidence-side base, the emission-side optical fiber exposed at the coupling end surface of the emission-side base and the incidence-side optical fiber exposed at the slope of the incidence-side base are spaced apart with a clearance (D), and the emission-side optical fiber and the incidence-side optical fiber are optically coupled. <IMAGE> |
