英文摘要	It is an object of the present invention to provide a light sending and receiving module by a ferrule, a connecting device of the light sending and receiving module and a method of manufacturing the light sending and receiving module characterized in that: the light sending and receiving module is interposed between the butting faces of the optical fibers without embedding an optical filter; deterioration of the optical characteristic can be prevented by eliminating a gap between the optical fiber and the optical filter; the number of ferrules is decreased so as to reduce the manufacturing cost; and further the size can be reduced by omitting an adapter. According to the present invention, there are provided a ferrule joining member (1A), in which a portion or all of the circumferential face of an optical fiber (4) is exposed from an end portion of the ferrule in which the optical fiber (4) is embedded, and a guide sleeve (2A) for positioning into which the ferrule joining member (1A) is inserted. When end faces of the optical fibers (4) are butted to each other via an optical filter (5) so as to conduct light branching, the optical fibers (4) are optically coupled to each other. Due to the above structure, no gaps are formed between the optical fiber (4) and the optical filter (5). Therefore, the occurrence of irregular reflection can be prevented.
