Abstract
The present invention provides an electric power generation method using a thermoelectric power generation element, a thermoelectric power generation element, and a thermoelectric power generation device, each of which has high thermoelectric power generation performance and can be used for more applications. The thermoelectric power generation element includes a first electrode and a second electrode that are disposed to oppose each other, and a laminate that is interposed between the first and second electrodes and that is electrically connected to both the first and second electrodes, where the laminate has a structure in which SrB6 layers and metal layers containing Cu, Ag, Au, or Al are laminated alternately, a thickness ratio between the metal layer and the SrB6 layer is in a range of metal layer: SrB6 layer=20:1 to 2.5:1, lamination surfaces of the SrB6 layers and the metal layers are inclined at an inclination angle θ of 20° to 50° with respect to a direction in which the first electrode and the second electrode oppose each other, and a temperature difference applied in a direction perpendicular to the direction in the element generates a potential difference between the fi…
