PROBLEM TO BE SOLVED: To provide an optical waveguide structure equipped with an optical waveguide having wide degree of freedom of design of pattern configuration and capable of forming a core part (optical path) having high dimensional accuracy by a simple method. SOLUTION: The optical waveguide structure 9 comprises an optical waveguide 90 having a core layer 93 equipped with a core part 94 and a clad part 95 having a refractive index lower than that of the core part 94, and conductor layers 901 and 902 provided on both faces of the optical waveguide 90. The core layer 93 is constituted by including as a main material, a norbornene-based polymer having a main chain and a leaving group branched from the main chain and capable of leaving at least part of a molecular structure from the main chain, and refractive indexes of the core part 94 and the clad part 95 are different because numbers of the leaving groups in a state bonded to the main chain are different.
