PROBLEM TO BE SOLVED: To provide a wiring board for vehicle which can surely interrupt short circuit current between the +pole and -pole of a battery through a capacitor when the capacitor breaks down while the increase of the cost is suppressed. SOLUTION: The capacitors 7 and conductive pastes 8, which are connected in series, are connected between a +B line 3 and a GND line 6, between an IG+ line 4 and the GND line 6, and between a +B line 5 and the GND 6 via the +B line 3 and the IG+ line 4, respectively. Namely, one of the two capacitors 7 connected in series is substituted for the conductive paste 8 in a conventional vehicle wiring board. Thus, a printed board 1 which can surely suppress that various electric components and an electric device, which are mounted on the printed board 1, are damaged due to shorting of the +pole and the -pole of the battery 13 when the capacitor 7 breaks down while the increase of the cost is suppressed, can be realized by exchanging one capacitor 7 for more inexpensive conductive paste 8.
