PRINTED CIRCUIT BOARD FOR OPTICAL WAVEGUIDES AND METHOD OF MANUFACTURING THE SAME

摘要

PURPOSE: A printed circuit board and a manufacturing method thereof are provided to remarkably reduce the amount of a core material and a clad material which are used for the formation of an optical waveguide. CONSTITUTION: An insulating layer(500) includes a laminated penetrated hole on a lower substrate(100). An optical waveguide is formed between the inner wall of the penetrate hole at an interval. An adhesive layer(700) is filled in the interval.
