A method of manufacturing an optical waveguide comprises a first step of laminating, on one major surface of a first glass material, a second glass material to a desired thickness, the second glass material having optical characteristics different from those of the first glass material, a second step of forming the second glass material to have a desired circuit pattern, and a third step of laminating a third glass material having optical characteristics similar to those of the first glass material on an entire surface of the first glass material on which the circuit pattern is formed by the second glass material. In at least one of the first and third steps, the glass material to be laminated is laminated by coupling.

[ What is claimed is:] [1.] A method of manufacturing an optical waveguide comprising:a first step of laminating, on one major surface of a first glass material having a first glass transition point, a second glass material to a desired thickness, said second glass material having optical characteristics different from those of said first glass material and having a second glass transition point lower then said first glass transition point;a second step of removing a non-circuit-pattern portion of said second glass material and forming a desired circuit pattern by said second glass material laminated on said first glass material to said desired thickness; anda third step of placing, on an overall surface of said first glass material with said second glass material of a desired circuit pattern formed thereon, a third glass material having optical characteristics similar to those of said first glass material and having a third glass transition point lower than said first and second glass transition points, and pressing said third glass material against said first glass material while heating said first through third glass materials at a temperature near said second glass transition point, thereby substantially maintaining said desired circuit pattern on said first glass material, and covering said first and second glass materials with said third glass material, with the non-circuit-pattern portions of said first glass material filled with said third glass material, on which the second glass material does not exist.
