<p><P>PROBLEM TO BE SOLVED: To provide a current detector that facilitates attachment to a current path while simplifying and miniaturizing the configuration, and accurately determines a failure of a Hall element without being affected by an external magnetic field. <P>SOLUTION: An electromagnetic shield frame member 14 is formed so that the intensity of a magnetic field generated from a bus bar 11 has a symmetric distribution with respect to the plane A orthogonal to the segment interconnecting two magnetic detectors 15 and 16 in the electromagnetic shield frame member 14 when the electromagnetic shield frame member 14 is mounted to the bus bar 11. Two magnetic detectors 15 and 16 are arranged at symmetric positions with respect to the plane A. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
