1. A position detection device, comprising a thermoelectric conversion portion including a magnetic layer having magnetization and a plurality of electrodes which are made of a material having spin-orbit interaction and are formed on the magnetic layer so as to extend in a direction intersecting a magnetization direction of the magnetic layer,wherein the thermoelectric conversion portion modulates an effective temperature in the magnetic layer so as to induce a spin Seebeck effect when an arbitrary location on a layer-surface of the magnetic layer is heated, and generates a voltage corresponding to a heated position from the plurality of electrodes as position information.
