Abstract: This spin current magnetization rotational element includes a first ferromagnetic metal layer for a magnetization direction to be changed, and a spin-orbit torque wiring extending in a second direction intersecting a first direction which is an orthogonal direction to a surface of the first ferromagnetic metal layer and configured to be joined to the first ferromagnetic metal layer, wherein the spin-orbit torque wiring has a structure in which a spin conduction layer joined to the first ferromagnetic metal layer and a spin generation layer joined to the spin conduction layer on a surface on a side opposite to the first ferromagnetic metal layer are laminated.
