<P>PROBLEM TO BE SOLVED: To provide an optical wiring board and a laser beam multiplexing module which have a small body, are easily mounted, and can effectively reduce speckle noise; and a projector using those. <P>SOLUTION: On an optical wiring board, one flexible substrate, a plurality of cores which is formed on the flexible substrate and functions as a transmitting path of an optical signal, and a clad, covering a surface of the flexible substrate on which the cores are arranged and the plurality of the cores, are integrally configured. End surface of the plurality of the cores is arranged on one end surface side of the flexible substrate, and one uniting core is formed by optically uniting the plurality of the cores near the other end surface side of the flexible substrate. An end surface of the uniting core is arranged on the other end surface side of the flexible substrate. <P>COPYRIGHT: (C)2012,JPO&INPIT |
