PROBLEM TO BE SOLVED: To provide attaching structure for a light emitting member capable of easily performing positional adjustment for the housing of the light emitting member. SOLUTION: A two-wavelength laser diode 102 is integrally composed with a package having a cylindrical stem 102a and external connecting terminals 102g, and an attaching part consisting of a storing chamber 106a which stores a cap part 102e of the two-wavelength laser diode 102 and an attaching hole 106b into which the stem 102a is force-fitted is formed in the housing 106. The two-wavelength laser diode 102 is attached to the housing 106 in the state of being positioned in the direction orthogonal to an axial center and also a V shaped groove 106m by which one end part 111a' of an adjusting jig is supported as a turning fulcrum is provided in the attaching hole 106b, and a recessed groove 102h by which the other end 111a" is locked is provided in the stem 102a. The inner wall of the recessed groove 102h is pressed with the other end part 111a" by the turning operation of the adjusting jig, and the rotational position of the two-wavelength laser diode 102 is adjusted by turning the stem 102a around the axial center. |
