Abstract

PURPOSE: To obtain the magnetic field detecting element with high sensitivity and broad dynamic range, by locating the high permeability substance of strip shape shorter than the MR element at both sides or one side via a gap, in the magnetic field detecting element consisting of a plurality of MR elements of strip shape formed on the substrate.
CONSTITUTION: The MR element 8 strip shape W1 in width is formed on the substrate with a gap G and the high permeability substance 12 in shorter width W2 than W1 at both sides together with the conductor terminals 10 and 11. One side of the conductor terminals 10, 11 is connected to the current supply source 14 and another is connected to the output terminal 15. To the magnetic field HX broadwise fed to the MR element 8, the sensitivity of the part 9' having the high permeability substance at both side is higher than other part 9. Accordingly, the output of the part 9 does not show the saturation to the saturated magnetic field to the part 9'. The pair like these can be plurally located in the interval of 1/4 of the bit length P. Thus, the dynamic range can be made broader with high sensitivity.
