PROBLEM TO BE SOLVED : To provide a magnetoresistance effect element capable of stably operating, and to provide a manufacturing method of the same.
SOLUTION : A magnetoresistance effect element of one embodiment includes : a bottom electrode; a first magnetic layer; a first interfacial magnetic layer; a second interfacial magnetic layer; a second magnetic layer; and an upper electrode. The first magnetic layer is disposed on the bottom electrode. The first interfacial magnetic layer is disposed on the first magnetic layer. The non-magnetic layer is disposed on the first interfacial magnetic layer. The second magnetic layer is disposed on the second interfacial magnetic layer. The upper electrode is disposed on the second magnetic layer. The first magnetic layer is one of a magnetization storage layer and a magnetization reference layer, and the second magnetic layer is the other. The upper electrode includes an alloy layer or a mixture layer of precious metal and a transition element or a rare earth element, or a conductive oxide layer.
