PROBLEM TO BE SOLVED: To align optical fibers accurately with a low cost in manufacturing an optical fiber collimator. SOLUTION: An obliquely cut end face 101a of an optical fiber 101 is inserted into the recess 102a of a collimator lens 102 to perform optical axis alignment and positioning of the end face 101a to the focal point of the collimator lens 102. Subsequently, proximity of the recess 102a of the collimator lens 102 is softened by electric discharge 105, joining the optical fiber 101 with the collimator lens 102. According to this step, there is no need of moving a positional relation between the optical fiber 101 and the collimator lens 102 after the alignment, which prevents optical axis deviation and the positional deviation of the end face 101a of the optical fiber 101 from the focal point position of the collimator lens 102. In addition, the number of components is reduced, so that lower cost can be achieved. COPYRIGHT: (C)2007,JPO&INPIT
