An optical transmission/reception module includes a substrate, a light-receiving element provided on said substrate, a light source provided on the substrate, an optical waveguide that is formed on the substrate and has a turnaround point, and a filter positioned between the optical waveguide and the light-receiving element. The optical waveguide is optically connected to the light source at one end and is optically connected to the light-receiving element at the turnaround point. There is a stray-light elimination section in the substrate between the light-receiving element and the aforementioned one end of the optical waveguide.
