Abstract: [Object] To provide a thermoelectric power generation device that efficiently utilizes thermal energy/heat flow passing through a power generation module/heat flow sensor.
[Solving Means] It includes a plurality of magnetic wires 21 that is formed of a single magnetic material with large thermoelectric power due to an anomalous Nernst effect and is arranged in parallel on one surface of an insulation film 22; a plurality of non-magnetic wires 23 or a plurality of diamagnetic wires 27 arranged in parallel on the other surface of the insulation film 22 so as to be parallel or oblique to a direction in which the plurality of magnetic wires 21 is extended; through contact holes 24 that pass through the insulation film 22 and electrically connect the plurality of magnetic wires 21 and the plurality of non-magnetic wires 23 or the plurality of diamagnetic wires 27 so that a first magnetic wire 21a and a second magnetic wire 21b adjacent to each other, of the plurality of magnetic wires, can be connected in series via the plurality of non-magnetic wires 23 or the plurality of diamagnetic wires 27; and a substrate 20 that is formed of an insulating material or a conductive material coated with an insulating material, holds a stacked body of the plurality of magnetic wires 21, the insulation film 22, and the plurality of non-magnetic wires 23 or the plurality of diamagnetic wires 27, and is in thermal contact with the stacked body.

Abstract: [Object] To provide a thermoelectric body that can be deposited on any substrate, which is not limited to a single crystal bulk material or an epitaxially grown thin film, and is capable of exhibiting high coercive force and residual magnetization with respect to in-plane magnetization.
[Solving Means] A thermoelectric body that is a magnetic film for use in a thermoelectric generation element utilizing an anomalous Nernst effect, characterized by having an easy axis of magnetization in an in-plane direction and an amorphous structure. Favorably, the thermoelectric body is characterized in that SmpCo100-p (0
