A manufacturing method of an optical waveguide module which is capable of forming a light reflecting portion with stabilized accuracy and which is good in production efficiency. The manufacturing method of an optical waveguide module in which an optical element is mounted on the back side of end portions of an optical waveguide is provided. For the production of the above-mentioned optical waveguide, end portions of an over cladding layer 6 corresponding to the end portions of the optical waveguide are formed so as to serve as reflective portions 6a at the same time that the over cladding layer 6 is formed on the front side by a die-molding process using a molding die 10 so as to cover a core 5. |
