PROBLEM TO BE SOLVED: To provide an optical fiber attitude detector and an optical fiber attitude detection method which enhance accuracy and work efficiency of positioning of an optical fiber. SOLUTION: The optical fiber attitude detector is provided with: an illuminator 4 as a light projection means which irradiates the optical fiber 1b and a fixing member 2 with light from the side opposite from the fixing member 2 with the optical fiber 1b interposed between the illuminator and the fixing member; a camera 3 as an imaging means which images the optical fiber 1b and the fixing member 2 from the side opposite from the fixing member 2 with the optical fiber 1b interposed between the camera and and the fixing member; and a control part 6 which detects attitude of the optical fiber 1b based on light intensity distribution of a side of the optical fiber 1b obtained by performing image processing of an image of the camera 3. Thus, since it is not necessary to check the attitude of the optical fiber 1b by visual observation, the accuracy and the work efficiency of positioning of the optical fiber 1b are enhanced in comparison with the case of checking the attitude of the optical fiber 1b by the visual observation.
