<P>PROBLEM TO BE SOLVED: To provide a wiring substrate, an image forming apparatus, and a wiring method, which easily suppresses noise radiation from a signal propagating on the substrate at low costs without adding circuits or the like. <P>SOLUTION: The wiring substrate 100 has a pair of signal lines L parallel to each other and having constant distance to transmit a differential signal. The pair of signal lines L has a serpentine wiring pattern 400 which keeps the same length of the signal lines, and is provided with a connection means 500 which is mounted so that the same signal lines of the pair of signal lines L are short-circuited at the inside of the curve of the serpentine wiring pattern 400. The position of the connection means 500 is adjusted to an arbitrary position at the inside of the curve so that a phase difference of each signal of differential signals after passing the serpentine wiring pattern 400 becomes 180 degrees. <P>COPYRIGHT: (C)2010,JPO&INPIT |
