Summary:PROBLEM TO BE SOLVED: To provide a circuit board capable of using a DC measurement having high stability of a measurement at low cost in the measurement of the fault of a circuit board, and to provide a method for detecting the short circuit fault on the circuit board. SOLUTION: The circuit board comprises a plurality of elements and wirings for connecting between the elements on a board. The circuit board further comprises an independent detecting wiring not connected to the element and the wiring and formed at least at one position between the adjacent elements, between the adjacent element and wiring and between the adjacent wirings. Thus, the short circuit fault is detected by measuring DC conduction between the element and the wiring, and the independent detecting wiring.
