A spin current magnetization rotational element includes: a first ferromagnetic metal layer for a magnetization direction to be changed; and a spin-orbit torque wiring. The spin-orbit torque wiring has a structure in which a spin conduction layer and an interfacial spin generation layer are alternately laminated in the first direction, the number of a plurality of the interfacial spin generation layers is two or greater, and in the spin-orbit torque wiring, one of the plurality of interfacial spin generation layers is closest to the first ferromagnetic metal layer.
