PROBLEM TO BE SOLVED: To provide a printed circuit in which the erroneous operation of an electronic apparatus mounted on a printed board is prevented. SOLUTION: When an angleθbetween transmission lines 13ps and 13p1 is acute, a notch N is formed in the vicinity of a branch D by notching the transmission line. A transmission signal is reflected on the end face of the notch N and the strength of a signal reflected to a point P1 is substantially equalized to the strength of a signal reflected to a point P2. Consequently, the strength of a signal is prevented from lowering, thus preventing the erroneous operation of an electronic apparatus. COPYRIGHT: (C)2004,JPO
