A sealing structure of the thermoelectric conversion device, which has high sealing capability and is easy to manufacture, is provided. A thermoelectric conversion circuit utilizing Peltier effect is interposed between two metal heat exchanger plates. The O-ring interposed between the outer edge portions of the heat exchanger plates seals the gap formed between the outer edge portions of the heat exchanger plates along the whole periphery. The connector for connecting the thermoelectric conversion circuit to the external power supply is inserted into the through hole formed on the heat exchanger plate. The O-ring fitted on the connector seals the gap between the connector and the through hole spontaneously, when the connector is inserted into the through hole.

1. A thermoelectric conversion device comprising:a thermoelectric conversion circuit interposed between two plates, the plates respectively having an inner surface and an outer surface, wherein at least one of the two plates has a through hole from the inner surface to the outer surface through the plate; an outer edge sealing member for enclosing an outer periphery of the thermoelectric conversion circuit to seal a gap between outer edge portions of the two plates; a connector passed through the through hole and connected at one end to the thermoelectric conversion circuit for connecting the thermoelectric conversion circuit to an external power supply; and a connector sealing member that is constructed to seal a gap between the connector and the through hole spontaneously when the connector is inserted through the through hole and fixed at a prescribed position.
