A spin current magnetization rotational element includes: a first ferromagnetic metal layer having a variable magnetization direction; and a spin orbital torque wiring which is joined to the first ferromagnetic metal layer and extends in a direction crossing a direction perpendicular to a plane of the first ferromagnetic metal layer, wherein the spin orbital torque wiring is constituted of a non-magnetic material composed of elements of two or more kinds and a compositional proportion of the non-magnetic material has a non-uniform distribution between a first surface joined to the first ferromagnetic metal layer and a second surface located on a side opposite to the first surface.
