A thermoelectric generation method using a thermoelectric generator includes: placing a thermoelectric generator in a temperature-changing atmosphere; drawing to outside a current that is generated due to a temperature difference between first and second support members when the temperature of the second support member is higher than that of the first support member, and that flows from a second thermoelectric conversion member to a first thermoelectric conversion member, using first and second output sections as a positive terminal and a negative terminal, respectively; and drawing to outside a current that is generated due to a temperature difference between the first and second support members when the temperature of the first support member is higher than that of the second support member, and that flows from a fourth thermoelectric conversion member to a third thermoelectric conversion member, using third and fourth output sections as a positive terminal and a negative terminal, respectively.
