To provide an optical waveguide structure having an optical waveguide that enables a greater degree of freedom in pattern shape design, allows a core part (an optical path) to be formed with high dimensional precision by a simple method and is excellent in durability, and an electronic equipment.

An optical waveguide structure 1 includes an optical waveguide 9 formed by layering cladding layers 91 and 92 on both sides of a core layer 93, conductor layers 51 and 52 joined to the both sides respectively, an optical path conversion part 96 bending an optical path of the optical waveguide 9 at substantially right angle, a light emitting element 10 and an electrical element 12. The core layer 93 has a core part 94 and a clad part 95. A layer of the core part 94 is constituted of a composition containing a cyclic olefin resin (A), at least one of a monomer and an oligomer (B), each of which having a cyclic ether group and a different refractive index from a refractive index of the cyclic olefin resin (A), and a photoacid generator (C). The layer of the core part 94 is selectively irradiated with light so that the core part 94 is formed into a desired shape.
