PROBLEM TO BE SOLVED: To provide a print wiring board for attaining branched wiring structure for branching a high frequency noise off from main wiring at low cost. SOLUTION: One end of a resonance pattern 11a is connected to a power source pull-in pattern 7 which is electrically connected to a power source side through hole 6 and the other end is an open end. One end of a resonance pattern 11b is connected to a GND pull-in pattern 9 which is electrically connected to a GND side through hole 10 and the other end is an open end. A resonance filter 8 is provided with the resonance patterns 11a and 11b. COPYRIGHT: (C)2007,JPO&INPIT
