An optical waveguide film includes a film including a clad layer and a core layer covered by the clad layer; and an adhesive layer formed at least on one surface of the film, having a rough structured surface having an arithmetic mean surface roughness of 0.1 to 2.0 μm, and having a storage modulus at 25° C. of 10 to 100 MPa obtained by dynamic viscoelastic measurement in torsion mode with a frequency of 1 Hz.
