Abstract: A thermoelectric conversion element that has a power generation layer containing an iron-aluminum based magnetic alloy material containing equal to or more than 70 weight percent of iron and aluminum in total. The power generation layer generates an electromotive force, due to an anomalous Nernst effect that develops in the magnetic alloy material in response to a temperature gradient applied thereto, in a direction intersecting both the magnetization direction of the magnetic alloy material and the direction of the applied temperature gradient.

Abstract: Provided is a thermoelectric conversion element having a high Anomalous Nernst Effect at a lower cost. A thermoelectric conversion element (1) includes a magnetic alloy material containing aluminum, cobalt, and samarium, and a power generation layer (10), in which in the power generation layer (10), a content of aluminum in the magnetic alloy material is in a range of 1 atomic percent to 40 atomic percent, a content of samarium in the magnetic alloy material is in a range of 12 atomic percent to 40 atomic percent, and a content of cobalt in the magnetic alloy material is in a range of 57 atomic percent to 82 atomic percent.
