A spin current magnetization rotational magnetic element in which magnetization can be rotated without applying an external magnetic field, power saving and a degree of integration can be enhanced. The spin current magnetization rotational magnetic element includes a spin-orbit torque wiring in a first direction; a first ferromagnetic layer in a second direction, a magnetization direction of the first ferromagnetic layer being configured to change; and a spin injection layer which is in contact with a surface of the spin-orbit torque wiring on a side opposite to the first ferromagnetic layer side and laminated in the second direction, in which the magnetization direction of the first ferromagnetic layer is a Z direction and the magnetization direction of the spin injection layer is an X direction in the first direction.
