<p><P>PROBLEM TO BE SOLVED: To provide a printed circuit board whose cost of the product can be lowered since the need for separate connectors is obviated. <P>SOLUTION: The printed circuit board includes: a first board unit and a second board unit disposed with a gap in-between; and a flexible optical board configured to transmit optical signals, which has one side stacked on the first board unit and the other side stacked on the second board unit, wherein the flexible optical board includes a core through which the optical signals travel, a cladding surrounding the core, and a circuit pattern buried in the cladding which transmits electrical signals. The rigid boards and the flexible optical board are formed as an integrated structure. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
