Abstract
An object of the present invention is to provide a low-cost thermoelectric converter element having high productivity and excellent conversion efficiency. A thermoelectric converter element according to the present invention includes a substrate 4, a magnetic film 2 provided on the substrate 4 with a certain magnetization direction A and formed of a polycrystalline magnetically insulating material, and an electrode 3 provided on the magnetic film 2 with a material exhibiting a spin-orbit interaction. When a temperature gradient is applied to the magnetic film 2, a spin current is generated so as to flow from the magnetic film 2 toward the electrode 3. A current I is generated in a direction perpendicular to the magnetization direction A of the magnetic film 2 by the inverse spin Hall effect in the electrode 3.
