PURPOSE:To easily connect a connector to an optical fiber by assembling a ferrule, a stopper member, a spring, and a connector main body as a subassembly, and inserting an optical fiber into the ferrule from behind and adhering it. CONSTITUTION:The connector main body 34 has a small-diameter fitting hole 36 where the base-end small-diameter part 18 of the ferrule 12 is fitted at one end side, a large-diameter fitting hole 38 where the intermediate large-diameter part 16 of the ferrule 12 is fitted at the intermediate part, and an edge hole 40 where the screw part 30 of the stopper member 24 is engaged threadably at the other end side. The coil spring 44 is interposed between the intermediate large-diameter part 16 of the ferrule 12 and the step part 42 of the connector main body 34 and the connector main body 34 is engaged threadably with the stopper member 24 so that the ferrule 12 is put inside, thereby forming the subassembly. At this time, the base end small-diameter part 18 of the ferrule 12 projects from one end side of the connector main body 34. When the optical fiber is fitted to the ferrule, it is fitted to the optical connected formed as the subassembly, so the operability of the connection of the optical fiber is improved greatly.
