<p><P>PROBLEM TO BE SOLVED: To provide a printed circuit board which doesn't generate radiation noise due to discontinuity of a return current. <P>SOLUTION: A printed circuit board 1 includes: signal wiring 4 wired in a surface layer to connect an output part 2 and an input part 3; a first conductor 8 disposed on the side of the output part 2 in an inner layer just below the signal wiring 4; a second conductor 9 disposed on the side of the input part 3 in the inner layer just below the signal wiring 4; and a capacitor 13 for capacitive coupling between the first conductor 8 and the second conductor 9. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
