PROBLEM TO BE SOLVED: To provide an optical waveguide with which desired incident light is efficiently transmitted to a light emitting side and is emitted, and the propagation of undesired incident light is prevented, and to provide a light source module and an optical information processing device using the optical waveguide. SOLUTION: The optical waveguide 160 is composed of connected body of a substrate 1, a core layer 6 and clad layers 2 and 5, and so composed that the incident light to the core layer 6 is guided to the light emitting side, and a metallic layer 4 for preventing the propagation of incident light to the clad layers 2 and 5 to the light emitting side is formed on a pattern which shields the light transmitting cross section of the clad layers 2 and 5.
