摘要

PROBLEM TO BE SOLVED: To provide an optical wiring board which has less optical loss and which is satisfactory in assemblability and assembling accuracy.;SOLUTION: The optical wiring board is constituted by laminating: an electrical board 1 wherein a light-emitting element 4 converting an electric signal into light and a light-receiving element 5 converting light into an electrical signal are provided and electrical wiring is formed; an optical waveguide sheet 3, wherein one mirror face 6 and the other mirror face 7 are formed with a space, and an optical waveguide 8, transmitting the light reflected by the one mirror face 6 toward the other mirror face 7, is formed between the one mirror face 6 and the other mirror face 7; and a collimating lens sheet 2, which is interposed between the electrical board 1 and the optical waveguide sheet 3 and wherein a collimating lens 9 converting the light from the light-emitting element 4 into a parallel luminous flux and guiding it to the one mirror face 6 is formed.;COPYRIGHT: (C)2009,JPO&INPIT
