摘要： A production method of an optical waveguide for a connector is provided, which reduces an optical coupling loss. Cores are formed in a crossing pattern, a branched pattern or a linear pattern, and then an over-cladding layer formation photosensitive resin layer is formed over the cores. In turn, a heat treatment is performed at a temperature of 70° C. to 130° C. to properly form mixed layers in interfaces between the cores and the photosensitive resin layer. By thus forming the mixed layers, the connector optical waveguide can be produced as having a reduced optical coupling loss.

The optical connector comprises: an optical waveguide including cores for transmitting light, an under cladding layer provided under the cores, and an over cladding layer provided over the cores; and a ferrule section for optical connection provided in each end portion of the optical waveguide. Part of at least one of the over cladding layer and the under cladding layer lying in a location corresponding to each end portion of the optical waveguide is thick-walled to become the ferrule section for optical connection. A thin-walled part of the optical connector lying between the ferrule sections is an optical waveguide section.
