Abstract
PURPOSE:To regulating the length of a whole wiring pattern and to regulate a delay time by forming a single or a plurality of dummy wiring patterns for a wiring pattern for transmitting a signal, and disposing both so as to connect or separate them. CONSTITUTION:A plurality of dummy wiring patterns 5 are connected so as to be cut from a wiring pattern 4. Viaholes 6 are respectively formed near the cutting positions of the patterns 5. The lengths of the plurality of patterns 5 have different lengths, delay times corresponding to the lengths are known to minimize the number of connections or separations, and the delay time can be regulated accurately.
