ABSTRACT:
A current-perpendicular-to-plane magneto-resistive element includes a magneto-resistive film and a pair of upper and lower magnetic shielding films holding the magneto-resistive film therebetween for current feeding. The lower magnetic shielding film has an at least two-layer structure including a crystalline material layer and an amorphous material layer disposed below the crystalline material layer.
