PROBLEM TO BE SOLVED: To provide an optical waveguide capable of easily coupling to an optical connection component while saving space, an optical wiring component and an optical waveguide connection structure which are compact, include the optical waveguide, and have high optical coupling efficiency, and a highly reliable electronic apparatus including the optical waveguide.SOLUTION: An optical waveguide 1 includes a plurality of core parts 14, a plurality of side face clad parts 15 and mirrors 17. A refractive index distribution W of the optical waveguide 1 includes regions in which a second maximum value, a minimum value, a first maximum value, a minimum value and a second maximum value are arranged in this order. The minimum value is less than an average refractive index in the side face clad part 15, and a refractive index continuously changes as a whole. The refractive index distribution W is formed by partially irradiating, with alight, a layer composed of materials obtained by dispersing, in a polymer, monomer having a refractive index different from that of the polymer, and by unevenly distributing the monomer, and by causing a deviation of the refractive index in the layer. The positions of mirrors 17 provided on two adjacent core parts 14 are mutually shifted in a longitudinal direction of the core parts 14. |
