Patent number: 9343647Abstract: A position detection device includes a thermoelectric conversion portion which includes a magnetic layer and a plurality of electrodes. The magnetic layer has magnetization. The plurality of electrodes are formed of a material having spin-orbit interaction, and are formed on the magnetic layer so as to extend in a direction which intersects with the magnetization direction of the magnetic layer.
