摘要：
A method of manufacturing optical waveguide device, comprising steps of: preparing optical waveguide including under cladding layer and protruding core pattern formed on the under cladding layer; preparing mold having protrusions for shaping recesses for fitting with predetermined portions of the core pattern; preparing board provided with light-receiving/emitting element mounted thereon; placing the mold around the light-receiving/emitting element for positioning top surfaces of the protrusions of the mold over light-receiving/emitting portions of the light-receiving/emitting element; filling the mold with sealing resin material and hardening the material in the mold to form sealing resin layer having recesses for fitting with the core pattern; after removing the sealing resin layer from the mold, the core pattern are fitted with the recesses of the resin layer to optically couple the light-receiving/emitting portions and the optical waveguide; and forming an over cladding layer for covering the remaining portion of the core pattern.
