Claim:
A method of laminating an ultraviolet curing type waveguide material, comprising the steps of: interposing a first optical waveguide material and a base plate between a first film and a second film, the first and second films being flexible; decompressing between the first film and the second film so that the second film fits a surface of the first optical waveguide material and side surfaces of the base plate and the first optical waveguide material; applying an external air pressure to the second film through a pressurization such that a uniform load is applied to the surfaces of the first optical waveguide and the base plate, and at the same time irradiating ultraviolet rays on the first optical waveguide material through the first film to cure the first optical waveguide material, such that a first laminated product constituted by the base plate and the first optical waveguide material is formed; placing a second optical waveguide material on the first optical waveguide material of the first laminated product, and interposing the second optical waveguide material and the first laminated product between the first film and the second film; decompressing a space between the first film and the second film so that the second film follows a surface of the base plate and side surfaces of the base plate, the first optical waveguide material and the second optical waveguide material; irradiating ultraviolet rays on the second optical waveguide material from the outside of the first film through a mask to carry out patterning at the same time of laminating the second optical waveguide material on the first optical waveguide material by applying an external pressure to the second film using an outside air, after decompressing the space between the first film and the second film, such that a second laminated product constituted by the base plate, the first optical waveguide material and the second optical waveguide material is formed; placing a third optical waveguide material on the second optical waveguide material of the second laminated product, and interposing the third optical waveguide material and the second laminated product between the first film and the second film; decompressing a space between the first film and the second film so that the second film follows a surface of the third optical waveguide material and side surfaces of the base plate, the first optical waveguide material, and the third optical waveguide material; and irradiating ultraviolet rays on the third optical waveguide material from the outside of the first film at the same time of laminating the third optical waveguide material on the second optical waveguide material by applying an external pressure to the second film using an outside air, after decompressing the space between the first film and the second film.
