A method of manufacturing a film waveguide includes molding a first clad layer formed with a concave groove for core filling, molding a second clad layer, and laminating the surface formed with the concave groove of the first clad layer and the second clad layer using resin. The resin has a flexural modulus of smaller than or equal to 1,000 MPa, contains hydrogen bonding group in a functional group of a precursor, and has a refraction index higher than the clad layers. A core is formed in the concave groove by the resin.
