<p><P>PROBLEM TO BE SOLVED: To provide a current sensor capable of reducing isotropic dilation due to temperature and the like or measuring error due to distortions. <P>SOLUTION: While an half bridge circuit 7a is arranged at one side region divided to a center line 3 of an installed base 2, an half-bridge circuit 7b is arranged to the other side domain, and both the half-bridge circuits 7a and 7b are configured as a point symmetry mutually to be arranged to the center point 4 of the installed base 2. Even if isotropic elongation or distortion is generated on the installed base 2 of magneto-resistive effect elements 5a to 5c due to the temperature and the like, since the half-bridge circuit 7a and the half-bridge circuit 7b are influenced equally due to elongation or distortions, a bridge circuit 8 can offset such influences and can reduce the measurement errors due to the isotropic elongation or distortions caused by the temperature and the like. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
