A spin-orbit-torque magnetization rotational element includes: a spin-orbit torque wiring layer which extends in an X direction; and a first ferromagnetic layer which is laminated on the spin-orbit torque wiring layer, wherein the first ferromagnetic layer has shape anisotropy and has a major axis in a Y direction orthogonal to the X direction on a plane in which the spin-orbit torque wiring layer extends, and wherein the easy axis of magnetization of the first ferromagnetic layer is inclined with respect to the X direction and the Y direction orthogonal to the X direction on a plane in which the spin-orbit torque wiring layer extends.
