<p><P>PROBLEM TO BE SOLVED: To solve the problems on a conventional current sensor having a thin film coil in which a measured current flows, installed opposite to and adjacent to magnetic resistance effect elements, for measuring a weak current flowing in an adjacent measured current wire, that it is of such a coil type that a conductor in which the measured current flows is constructed in the same plane, and so a turn-around portion for circulation and a portion, not opposed to the magnetic resistance effect elements in which the measured current flows in the opposite direction, are unnecessary for constructing the sensor and disadvantageous in reducing the size because of an increased surface area. <P>SOLUTION: This current detecting device includes the measured current wire consisting of measured conductor installed opposite to the magnetic resistance effect elements and a through-connecting current wire connecting these together for coiling the magnetic resistance effect elements outside the plane. Thus, the current detecting device has an effectively reduced size. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
