A magnetization rotational element includes a spin-orbit torque wiring, and a first ferromagnetic layer which is located in a first direction with respect to the spin-orbit torque wiring and in which spins are injected from the spin-orbit torque wiring. The spin-orbit torque wiring has a plurality of spin generation layers and insertion layers located between the plurality of spin generation layers in the first direction. The insertion layers have a lower electrical resistivity than the spin generation layers.
