A thermoelectric converter has a N-type thermoelectric element, a P-type thermoelectric element, an endothermic electrode and a radiative electrode. One surface of the N-type thermoelectric element is attached to one surface of the endothermic electrode and the other surface is attached to one surface of the radiative electrode. One surface of the P-type thermoelectric element is attached to the other surface of the radiative electrode and the other surface is attached to the other endothermic electrode.
