The present invention provides an optical waveguide having a low temperature dependence of the difference in refractive index between a core resin and a clad resin and exhibiting excellent optical properties in all the operating temperatures. An optical waveguide of the present invention includes cured resin products each containing, as constituent components, first fluorine-containing monomers each having a perfluoroadamantane structure. With this arrangement, it is possible to obtain an optical waveguide that is excellent in both optical properties and temperature dependence of difference in refractive index between a core resin and a clad resin.
