2. A method for manufacturing an optical waveguide film comprising the steps of:
forming a core layer; and

3. A method for manufacturing an optical substrate comprising the steps of:
forming a first positioning mark in a supporting substrate;
forming a second positioning mark corresponding to the first positioning mark in an optical waveguide film comprising a clad layer having an adhesive function and a core layer covered by the clad layer;
positioning the optical waveguide film to the supporting substrate by the first positioning mark and the second positioning mark, with a surface of the supporting substrate being in contact with a surface of the clad layer; and
curing the clad layer of the positioned optical waveguide film by heating and pressurizing, so that the optical waveguide film is adhered to the supporting substrate.
4. A method for manufacturing an optical substrate comprising the steps of:
positioning an optical waveguide film comprising a clad layer having an adhesive function and a core layer covered by the clad layer, to a supporting substrate so that optical axes between optical elements pass through the core layer, with a surface of the supporting substrate being in contact with a surface of the clad layer, and
curing the clad layer of the positioned optical waveguide film by heating and pressurizing, so that the optical waveguide film is adhered to the supporting substrate.
