PURPOSE:To easily constitute the optical waveguide array having rigidity without using optical fibers by integrally forming the optical waveguide having many optical waveguides. CONSTITUTION:A plate material 1 having three-layered structure formed with a flat plate core part 1a consisting of polycarbonate having a light transparent characteristic and a clad part 1b coated with polymethyl methacrylate having the refractive index smaller than the refractive index of the polycarbonate from above and below this core part is formed. An adhesive agent 4 is applied on the surfaces of the many projections of a base material 2 and the plate material 1 having such three-layered structure is placed thereon. The material is then pressed from above by a metallic mold 3. The pressed plate material 1 having the three-layered structure is partly filled in the groove parts of the base member 2 and partly remains on the projections of the base member 2, by which the fresh grooves are formed in the plate material 1. The optical waveguide 5 having the many waveguide parts 5a is integrally formed if these groove parts are packed with the same material or the material having about the same refractive index as the refractive index of the clad part 1b. |
