<p><P>PROBLEM TO BE SOLVED: To provide a method of manufacturing an optical waveguide device which provides the excellent smoothness of a light receiving end surface and a light emitting end surface formed by cutting and which provides excellent productivity. <P>SOLUTION: A laminate of a film element 2 and a board 1 is die-cut from the side of the board 1, wherein the film element 2 includes at least one future optical waveguide portion 20 and wherein the board 1 is stacked on the film element 2. This provides an optical waveguide device including the die-cut board 1 and an optical waveguide formed thereon. A cutting die used for the die-cutting includes at least blades 3 for forming the light receiving end surface 20a and the light emitting end surface 20b of the optical waveguide. The blades 3 are flat blades including blade surfaces 3a having an arithmetic means roughness (Ra) of less than 0.02μm. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
