    • PROBLEM TO BE SOLVED: To provide a manufacturing method of optical waveguide device capable of suppressing the surface roughening of core side surfaces of an optical waveguide, even if an optical waveguide is formed on the surface of a PET substrate, and to provide an optical waveguide device obtained by the manufacturing method. SOLUTION: The manufacturing method of optical waveguide device includes: a step of forming an under cladding layer 2 on the surface of a PET substrate A with a colored layer composed of a PET substrate 1 part and a colored layer 5 of a color capable of absorbing irradiation light L, formed on the back surface of the PET substrate 1 part; a subsequent step of forming a photosensitive resin layer 3A for core 3 formation; a later step in which the photosensitive resin layer 3A is irradiated with the irradiation light L, to form an exposed prescribed pattern; and a core formation step of forming the exposed part into a core 3. In core 3 formation step, when the irradiation light L reaches the bottom surface of the PET substrate 1 part, a greater part of the irradiation light L is absorbed in the colored layer 5 and, as a result, irradiation light L reflected at the bottom surface of the PET substrate 1 part almost can be suppressed. Accordingly, the irradiation light L, which is irregularly reflected on the PET substrate 1 part and reaches the photosensitive resin layer 3A, is significantly reduced, and the surface roughening of the core 3 side surface is effectively suppressed.

    • PROBLEM TO BE SOLVED: To provide a method of manufacturing optical waveguide device capable of reducing light propagation losses in a core of an optical waveguide regardless of the type of the substrate when the optical waveguide is formed on the surface of the substrate. SOLUTION: When using a metal substrate 11 or the like, irradiation rays L for forming the core are irregularly reflected due to the metal substrate 11 or the like and a side 3a of the core 3 is formed into a roughened surface. However, in the subsequent step, (a second) photosensitive resin layer 4A for forming an over-cladding layer is formed with a non-solvent type photosensitive resin composition and is heated prior to exposure and, thereby, the interface part between the core 3 and the photosensitive resin layer 4A is formed into a mixed layer 5. By forming the mixed layer 5, light scarcely propagates to the side 3a part of the core 3 formed on the roughened surface, therefore, the propagating light is scarcely affected by the roughened surface of the side 3a of the core 3 and the propagating loss of the light is reduced.

    • PROBLEM TO BE SOLVED: To provide a method for manufacturing a light guide device for suppressing roughening of a core side face of a light guide when forming the light guide on the surface of a substrate. SOLUTION: The method for manufacturing the light guide device includes: forming a photosensitive resin layer 3A for forming a core 3 through formation of an under-clad layer 2 on the surface of the substrate (A) whose surface is smooth in a range of 1-2 nm of an arithmetic average roughness (Ra); then, irradiating the photosensitive resin layer 3A with an irradiation ray L at a right angle to be exposed on a prescribed pattern; forming its exposure part on the core 3; and allowing the irradiation ray L transmitting the photosensitive resin layer 3A for forming the core 3 and the under-clad layer 2 to be reflected at a substantially right angle to the substrate (A) on the smooth surface of the substrate (A) in a process for forming the core 3, thereby significantly reducing random reflection on the surface of the substrate (A) to effectively suppress roughening of the side face of the core 3.
