<p><P>PROBLEM TO BE SOLVED: To provide a method of manufacturing an optical sensor module which eliminates the need for the operation of alignment between a core in an optical waveguide unit and an optical element in a substrate unit and which does not deteriorate the accuracy of alignment even when the thickness of a protruding portion is less than 50μm, and to provide the optical sensor module obtained thereby. <P>SOLUTION: An optical waveguide unit W<SB>2</SB>including protruding portions 4 having vertical walls with a height less than 50μm and groove portions 3b, and a substrate unit E<SB>2</SB>including positioning members P of respective positioning plate portions 5a to be positioned in the protruding portions 4 and fitting plate portions 5b to be fitted to the groove portions 3b are individually produced. Corners of the positioning members P are positioned on the vertical walls of the protruding portions 4, and the fitting plate portions 5a are fitted to the groove portions 3b, and they are integrated. In this case, the protruding portions 4 are formed at appropriate positions relative to the end face 2a for optical transmission and reception of a core 2. Also, the positioning members P are formed at appropriate positions relative to the optical element 8. Thus, the end face 2a for the optical transmission and reception of the core and the optical element 8 are automatically aligned. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
