Patent ID: 7294292

Claim:
A process for producing a polymer optical waveguide, comprising: preparing a mold comprising a concave portion for forming a core; bringing a cladding substrate into close contact with the mold, filling the concave portion of the mold with a core-forming curable resin; curing the core-forming curable resin in the concave portion to form a core on the cladding substrate; removing the mold from the cladding substrate on which the core has been formed; and forming a clad layer on a core-formed surface of the cladding substrate; wherein the mold includes a cured mold-forming resin layer and a reinforcing member for reinforcing the cured mold-forming resin layer, the cured mold-forming resin layer having the concave portion, the reinforcing member comprising material different than the mold-forming resin layer and having an introduction portion which communicates with the concave portion, an injection inlet for injecting the core-forming curable resin into the mold, wherein a space exists between the cured mold-forming resin layer and the reinforcing member, and wherein the mold includes a discharge portion which communicates with the concave portion and is provided in at least one of the reinforcing member and the cured mold-forming resin layer.
