An optical waveguide film and an electrical and optical hybrid circuit film having a high durability for folding while keeping the core size of the optical waveguide at a desired level are provided. The optical waveguide film is flexible, having a core made of a resin that composes an optical waveguide, a clad made of a resin, and a hollow groove extending in the same direction in which the core extends wherein at least at a portion of the optical waveguide film is folded so that the folding axis intersects with the core-extending direction at the portion. The films can contribute to the miniaturization of electronic devices.
