ABSTRACT:
In the present invention, a thin film whose main component is a metal having a specific resistance of 4 μΩ·cm to 200 μΩ·cm is used as a nonmagnetic layer of a so-called CPP-GMR element. Therefore, even when an area of the element becomes limited, the element is not increased excessively in resistance. Thus, even when a magnetic gap is narrow, a large output can be obtained.
