<P>PROBLEM TO BE SOLVED: To provide a current sensor that has a function for detecting a failure and does not cause such a situation where despite breakage of a wiring pattern around a detection element, an output signal is output by considering that a current flows in a measuring object current detection member. <P>SOLUTION: The current sensor includes a failure detection coil 46 arranged nearby the measuring object current detection member 36 and a cancel coil 35 for detecting the breakage of the wiring pattern around the detection element 21. <P>COPYRIGHT: (C)2012,JPO&INPIT |
