PURPOSE:To eliminate the fluctuation at the time of soldering of an optical fiber by always bringing the optical fiber in the vicinity of an optical semiconductor element, into contact with a projecting part of a supporting base, and also, executing the soldering far in the rear separated from a supporting point which said fiber has come into contact with and fixing the optical fiber. CONSTITUTION:A part of a fiber holder 12 for always holding an optical fiber 11 is fixed in advance onto a substrate 10 being common to an optical semiconductor element 13, and brought into contact with a projecting part 14a of a supporting part 14a of a supporting base 14 for forming a supporting point positioned at a suitable gap against the optical semiconductor element 13. Subsequently, while holding this state, the optical axis adjustment is executed by using the contact part as the supporting point, and after the adjustment has been completed, the supporting base 14 and the fiber holder 12 are soldered and fixed by a soldering part 14b, at a position separated from a distance to the supporting point when it is seen from the optical semiconductor element 13, for instance, at a position which is distant by several times. In such a way, since the optical fiber 11 being in the vicinity of the optical semiconductor element 13 is always in a fixed state, the fluctuation of the soldering part 14b and the influence exerted on the tip of the fiber can be remarkably reduced. |
