Abstract:
1. A manufacturing method of an optical waveguide film comprising: preparing a mold which is formed of a cured layer of a mold-forming curable resin and is provided with a recessed portion corresponding to a protruding portion of the waveguide core and two or more through holes which are communicated with respective ends of the recessed portion; bringing a lower clad film into close contact with the mold; filling one of the through holes formed to communicate with one end of the recessed portion of the mold with core-forming curable resin, the mold being brought into close contact with the lower clad film, and filling the recessed portion of the mold with the core-forming curable resin by performing vacuum suction of the core-forming curable resin from the through hole formed to communicate with another end of the recessed portion of the mold; curing the core-forming curable resin and peeling off the mold from the lower clad film; forming a notched portion at a portion of the waveguide core, the notched portion having an optical path changing surface; and forming an upper clad film on the lower clad film on which a core is formed.
