A method of manufacturing an optical sensor module which eliminates the need for the operation of alignment between a core in an optical waveguide section and an optical element in a substrate section, and an optical sensor module obtained thereby. An optical waveguide section W 1 including groove portions (fitting portions) 4a for the positioning of a substrate section, and a substrate section E 1 including fitting plate portions (to-be-fitted portions) 5a for fitting engagement with the groove portions 4a are individually produced. The fitting plate portions 5a in the substrate section E 1 are brought into fitting engagement with the groove portions 4a in the optical waveguide section W 1 whereby the substrate section E 1 and the optical waveguide section W 1 are integrated together. |
