Provided is an optical fiber head which has a simple configuration and can highly precisely position and fix an optical fiber (10) to a casing (20), also can ensure the sufficient holding power of the casing to hold the optical fiber, and yet can be manufactured easily at a moderate price. An optical fiber head includes an optical fiber (10), a lens (30), and a casing (20) which accommodates and holds the optical fiber and the lens. The casing has a crimping portion (22) which holds the optical fiber accommodated in the crimping portion when a part of the crimping portion in the axial direction of the casing is plastically deformed such that the crimping portion is virtually equally reduced in diameter in a circumferential direction. The part of the optical fiber (10) which is held by the crimping portion (22) has a coating (13) to coat the core wire. The crimping portion (22) is provided at a back end side of the casing and spaced apart, in the axial direction, from a position of the leading end face of the optical fiber. |
