<p><P>PROBLEM TO BE SOLVED: To measure three-dimensional azimuth of a magnetic field and reduce the size of a magnetic sensor. <P>SOLUTION: A first magnetic sensor chip 2 sensing to two directional magnetic components of the magnetic field and a second magnetic sensor chip 3 sensing to at least one direction magnetic component of the magnetic field are provided. The magnetic sensor 1, whose magnetic chips 2 and 3 are fixed so that the sensing direction C of the second magnetic sensor chip crosses with an acute angle to a plane including the two sensing directions A and B of the first magnetic sensor chip, is provided. <P>COPYRIGHT: (C)2004,JPO</p> |
