PROBLEM TO BE SOLVED: To provide a simple and highly productive method to manufacture a polymer optical waveguide which is made highly precise and has a low waveguide loss. SOLUTION: The manufacturing method of waveguide includes the following processes (1) a casting mold having a plurality of recessed parts (both tip parts of the recessed parts are the infiltrating section and the ejecting section of core resin) is produced employing a master disk on which a plurality of projecting parts are formed, (2) a clad member is tightly contacted to the mold, (3) core resin is filled into the mold recessed parts from the infiltrating sections of the mold, (4) the filled-in resin is hardened and the mold is peeled off from the member and (5) a clad layer is formed on the member on which a core is formed. The mold is made of a layer in which mold forming hardening resin is hardened and the recessed parts, the infiltrating and ejecting sections are provided and has a hardened resin layer having common gap sections that are connected to all infiltrating sections/or all ejecting sections at its tip part and a strengthened member having an injecting part to reinfoprce the hardened resin layer and to force fit the core resin.
