摘要： An optical fiber connector includes a ferrule, an inserted optical fiber, an external optical fiber, and a pair of reinforcing members that pinches and reinforces a fusion-spliced portion of the other end portion of the inserted optical fiber and the front end portion of the external optical fiber. The reinforcing members include adhesion layer on the inner surface thereof which comes in contact with the other end portion of the inserted optical fiber and the front end portion of the external optical fiber. The adhesion layer is depressed at the position where the inserted optical fiber and the external optical fiber come in contact with each other so as to closely adhere to the outer circumferential surfaces of the optical fibers in the fusion-spliced portion.
