Abstract
Provided are a thermoelectric conversion element and a thermoelectric conversion module which can efficiently generate power by preventing heat from being accumulated in a cooling side even in a naturally cooled environment. The thermoelectric conversion element includes a substrate having a sheet-like low thermal conduction portion, a first high thermal conduction portion, and a second high thermal conduction portion, a thermoelectric conversion layer provided on the substrate, a coating layer covering the thermoelectric conversion layer, a third high thermal conduction portion which is provided on the coating layer, has thermal conductivity higher than that of the coating layer, and does not completely overlap the first high thermal conduction portion in a plane direction, and a pair of electrodes, in which the second high thermal conduction portion is thinner than the first high thermal conduction portion and separated from the first high thermal conduction portion in the plane direction, and at least a portion of the second high thermal conduction portion overlaps the thermoelectric conversion layer and the third high thermal conduction portion.
