摘要：
The present invention is to provide an optical waveguide capable of allowing a desired incident light to efficiently propagate towards the light emission side and to emit therefrom, and capable of preventing unnecessary incident light from propagating, and in providing a light source module and an optical information processing apparatus using the optical waveguide. The optical waveguide comprises a bonded member of a substrate, a core layer and cladding layers, configured to introduce an incident line coming into the core layer toward a light emission side thereof. A metal layer for preventing the incident light coming into the cladding layer from propagating to the light emission side is formed in a pattern intercepting a sectional plane of light transmission of said cladding layer.
