Abstract
Provided is a magnetoresistance effect element that suppresses re-adhesion of impurities during preparation and allows a write current to easily flow. The magnetoresistance effect element includes a first ferromagnetic layer, a second ferromagnetic layer; and a nonmagnetic layer interposed between the first ferromagnetic layer and the second ferromagnetic layer. In the magnetoresistance effect element, the nonmagnetic layer is a tunnel barrier layer constituted by an insulator, a side surface of the first ferromagnetic layer, a side surface of the second ferromagnetic layer and a side surface of the nonmagnetic layer form a continuous inclined surface in any side surface, and a thickness of inside the nonmagnetic layer is thicker than a thickness of outside the nonmagnetic layer.
