Abstract
An optical waveguide production method, employs a light-transmissive mold having higher dimensional accuracy for formation of an over-cladding layer. The mold for the formation of the over-cladding layer is unitarily produced by molding a light-transmissive resin with the use of a mold component having the same shape as the over-cladding layer. A recess formed in the mold by removing the mold component in the production of the mold serves as a cavity for the formation of the over-cladding layer. For the formation of the over-cladding layer, a photosensitive resin for the over-cladding layer is injected into the cavity of the mold, and exposed through the mold to be cured while a core formed in a predetermined pattern on a surface of an under-cladding layer is immersed in the photosensitive resin.
