Claim Text:
1. A position detection device, comprising: a thermoelectric conversion portion including: 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, wherein the plurality of electrodes are disposed in a matrix, including a first electrode group and a second electrode group that are perpendicular to each other, wherein the first electrode group and the second electrode group include electrodes disposed in parallel to one another, respectively, wherein the electrodes of the first electrode group have an angle of 45 degrees to the magnetization direction of the magnetic layer, and wherein the electrodes of the second electrode group have an angle of 45 degrees to the magnetization direction of the magnetic layer, and wherein a thickness of the plurality of electrodes disposed in the matrix are equal to a spin diffusion length of the electrode material.
