Abstract
A GMR element includes a fixed magnetic layer in which magnetization is fixed; a free magnetic layer in which magnetization is changed by an external magnetic field; and a spacer layer which is positioned between the fixed magnetic layer and the free magnetic layer, in which the free magnetic layer is formed by laminating a CoFe alloy and a CoFeB alloy. A current sensor uses the GMR element.
