Abstract: It is an object to obtain an optical connector capable of implementing a more reduction in a cost of a work for carrying out an assembly into a site optical fiber, and a method of assembling the optical connector. An almost sheet-like protecting member 17 for transmitting a light in a predetermined refractive index is stuck to a tip surface of a ferrule 3 having a fiber inserting hole 15 penetrating therethrough with the fiber inserting hole 15 covered, and an optical fiber 14 positioned by a positioning mechanism 5 to be coupled to a rear part of the ferrule 3 has a tip surface inserted through the fiber inserting hole 15 of the ferrule 3 to abut on the protecting member 17 with an elastic force.

Abstract: It is an object to obtain an optical connector capable of executing an assembling work safely and easily without causing a problem, for example, a breakage of an end face of a short optical fiber provided in a ferrule when assembling a site optical fiber, and a method of assembling the optical connector. In an optical connector having a ferrule 3 including a short optical fiber 12 and a positioning mechanism 5 for placing and fixing an optical fiber 14 to be connected to the short optical fiber 12 in a predetermined position, an end face of the short optical fiber 12 and that of the optical fiber 14 are matched with each other through an almost sheet-like protecting member 17 for transmitting a light in a predetermined refractive index and the optical fiber 14 is positioned by an application of an elastic force to the short optical fiber 12 side.
