PROBLEM TO BE SOLVED: To provide an optical waveguide structure that has much latitude of design of a pattern shape, that facilitates formation of a core (optical path) with a high dimensional accuracy, and that is equipped with an optical waveguide excellent in durability. SOLUTION: The optical waveguide structure 1 is equipped with a block-shaped optical waveguide body 2 and five light emitting elements 61-65. The optical waveguide body 2 is composed by laminating a plurality of cladding layers and a plurality of core layers in a prescribed order, wherein each core layer has a core part 94 and a cladding part 95 formed in a prescribed pattern. The core part 94 is a portion forming the optical path for transmission light and is three-dimensionally arranged inside the optical waveguide body 2. The core part 94 is, as the main material, of a resin composition containing, for example, a norbornene based resin. The core part 94 is formed into a desired shape by selectively irradiating the core layer 93 with an active radiation, wherein the core layer 93 is composed of a material whose refractive index varies by the irradiation of the active radiation or by further heating.
