Abstract: PROBLEM TO BE SOLVED: To make it possible to correct the deviation in alignment which occurs at the time of manufacturing a multichannel optical element module by providing the method with a step for assembling by utilizing laser welding and a step for forming at least one weld zone in the prescribed position of an optical fiber supporting base by utilizing the shrinkage effect of a welding section. SOLUTION: This method for correcting a laser corrects displacement by moving an optical fiber array 1 not only in horizontal (x), perpendicular (y) and axial (z) directions but in rotating (Rx, Ry, Rz) directions with respect to respective axes and utilizing the shrinkage effect of the welding section in order to correct the light alignment to all the directions. The optical fiber supporting base 20 includes erecting plates 21 which are erected on both sides apart a prescribed spacing in order to support an optical fiber ferrule in order to effectively apply such laser correction. These erecting plates 21 are formed to a thickness 21a as thin as about 300 to 400 micrometers and are easily shrunk by the irradiation with the laser beam, by which the regulation of the displacement is made possible.
