摘要： A magnetoresistance effect element includes a multilayer in which magnetic layers, mixture layers each constituted by a mixture of a ferromagnetic element and a non-ferromagnetic element, and nonmagnetic layers are stacked on each other so as to exhibit a magnetoresistance effect. In this element, each of the mixture layers is interposed between the magnetic layer and the nonmagnetic layer, and 2 (X.sub.1 /X.sub.n)/n is larger than 1.1 where n is the number of atomic layers of the mixture layer, X.sub.1 is the atomic concentration (%) of the ferromagnetic element of an atomic layer closest to the magnetic layer, and X.sub.n is the atomic concentration (%) of the ferromagnetic element of an n-th atomic layer closest to the nonmagnetic layer.
