On a single chip are formed a plurality of magnetoresistance effect elements provided with pinned layers having fixed magnetization axes in the directions that cross each other. On a substrate 10 are formed magnetic layers that will become two magnetic tunnel effect elements 11, 21 as magnetoresistance effect elements. Magnetic-field-applying magnetic layers made of NiCo are formed to sandwich the magnetic layers in plan view. A magnetic field is applied to the magnetic-field-applying magnetic layers. The magnetic field is removed after the magnetic-field-applying magnetic layers are magnetized in the direction shown by arrow A. As a result of this, by the residual magnetization of the magnetic-field-applying magnetic layers, magnetic fields in the directions shown by arrows B are applied to the magnetic layers that will become magnetic tunnel effect elements 11, 21, whereby the magnetization of the pinned layers of the magnetic layers that will become magnetic tunnel effect elements 11, 21 is pinned in the directions shown by arrows B.

摘要:
Data are input from a geomagnetic sensor that detects magnetic fields in three axial directions, and magnetic field data are measured on the basis of the input data. The measured magnetic field data are sequentially stored, and a determination is made as to whether a plurality of the magnetic field data thus stored lie within a same plane in a three-dimensional orientation space. When it has been determined that the plurality of the magnetic field data lie within the same plane in the three-dimensional orientation space, center coordinates of a circular arc where the stored magnetic field data lie are calculated, as provisional offset values, on the basis of the magnetic field data and in accordance with a predetermined algorithm. Magnetic field data measured after the calculation of the provisional offset values is corrected with the provisional offset values, and an arithmetic operation is performed for determining orientation data on the basis of the corrected magnetic field data.
