<p><P>PROBLEM TO BE SOLVED: To provide an optical waveguide assembly in which a plurality of optical waveguides having small eccentricity can be efficiently manufactured wherein a cutting pitch is not necessary to be changed and the optical waveguide assembly is cut with a constant cutting pitch for every cutting job even when an individual variation is included in the waveguide distance due to the contraction of a resin material, and to provide a reliable optical wiring having the optical waveguide obtained by cutting the optical waveguide assembly and an optical/electrical hybrid board and an electronic device. <P>SOLUTION: The optical waveguide assembly 1 includes a plurality of belt-like core parts 132 to 136 which extend in X-direction and stand in line in Y-direction and a plurality of belt-like side face clad parts 150 laying adjacent to the core parts. The plurality of optical waveguides are manufactured by cutting each side face clad part, each side face clad part 150 includes a change part of which the width continuously varies along X-direction and a belt-like cutting margins 1315 to 1365 which are parallel to X-axis, and the ratio of the length which is the width of the side face clad part subtracted by the width of the cutting margin at an arbitrary X-coordinate is constant among the side face clad parts. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
