ABSTRACT:
Magnetoresistive elements of ferromagnetic material having a high sensitivity and an excellent reliability have been manufactured. According to such an element, the sensitivity thereof can be enhanced by restricting the sheet resistance of wiring portions to a low value, and it is possible to prevent generation of an offset voltage due to a discrepancy in alignment by broadening the width of wiring portions at the connecting portions between magnetically sensitive members and the wiring portions to be wider than that of the magnetically sensitive members and arranging the connecting portions so as to be disposed in a geometrically symmetrical relationship therebetween. Such a structure is adapted for connecting the magnetically members and the wiring portions in a self-aligning manner.
