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, a magnetic filmprovided on the substratewith a certain magnetization direction A and formed of a polycrystalline magnetically insulating material, and an electrodeprovided on the magnetic filmwith a material exhibiting a spin-orbit interaction. When a temperature gradient is applied to the magnetic film, a spin current is generated so as to flow from the magnetic filmtoward the electrode. A current I is generated in a direction perpendicular to the magnetization direction A of the magnetic filmby the inverse spin Hall effect in the electrode
