Abstract: PROBLEM TO BE SOLVED: To relieve the tight adhesion force by the refractive index matching agent of a connector connection face, to improve attaching and detaching workability and to eliminate the insufficiency of pressing force in the connection of connector by providing the parts of a ferrule end face which do not come into contact with optical fibers with recessed parts. SOLUTION: The parts of the ferrule end face 12 which do not come into contact with the optical fibers 22 are provided with the recessed parts 40. The recessed parts 40 are formed by laser beam processing after molding of the ferrules 10. Since the laser is capable of executing processing without strains, the size of the ferrule 10 does not change even after the processing and the characteristic of the connector connection receives no adverse effect. The area of the end face 12 decreases by forming the recessed parts 40. Therefore, the adhesive power by the refractive index matching agent of the connector connection surface is relieved when the connector is applied to the multi-fiber connector of an all-plastic integral molding type. The pressing force per unit area increases and the insufficiency of the pressing force in the connection of the connector is eliminated.
