Abstract: An optical fiber device includes a rigid pipe (4) provided to cover the outer peripheries of a fixing joint portion (2) and an optical fiber (1). The tip portion (4a) of the rigid pipe (4) has a gap for providing flexibility between the optical fiber (1) and the tip portion (4a). Therefore, the rigid pipe (4) suppresses bending of the optical fiber (1) to avoid concentration of stress in the fixing joint portion (2) for fixing the optical fiber (1) to an optical unit section, thereby avoiding breakage of the optical fiber (1) in the fixing joint portion (2). The optical fiber device also includes a ferrule (3a) and is used to connect the optical fiber (1) to an optical unit (3b).
