<p><P>PROBLEM TO BE SOLVED: To provide a current sensor which has a wide range of current detection and moreover, which can carry out high accuracy detection in a low current range. <P>SOLUTION: In the current sensor, a case 2 contains, a first core 9 having a high saturation flux density, a first Hall element 12 for converting a magnitude value of a magnetic field passing through the first core 9 into a voltage value, a second core 10, having small magnetic hysteresis; and a second Hall element 13 for converting the magnitude value of a magnetic field passing through the second core 10 into a voltage value. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
