Thermoelectric conversion element and thermoelectric conversion module

A thermoelectric conversion element comprising:

• a substrate;
• a pair of electrodes formed to be arranged apart from each other on the surface of the substrate;
• an insulating layer formed between the pair of electrodes so as to be in contact with the substrate and to cover the edges on the sides where the pair of electrodes face each other;
• and
• a thermoelectric conversion layer composed of a p-type thermoelectric conversion layer containing an organic p-type thermoelectric conversion material, which is formed to cover at least a portion of one of the pair of electrodes, and an n-type thermoelectric conversion layer containing an organic n-type thermoelectric conversion material, which is formed to cover at least a portion of the other one of the pair of electrodes,
• wherein the p-type thermoelectric conversion layer and the n-type thermoelectric conversion layer have a separation region in which the thermoelectric conversion layers are arranged apart by the insulating layer, and a contact region in which the thermoelectric conversion layers are joined to each other in a part above the insulating layer.
