PROBLEM TO BE SOLVED: To provide a thermoelectric generator that can be reduced in size by packing thermoelectric conversion elements in a small space. SOLUTION: The thermoelectric generator includes a spirally-shaped first thermoelectric element 13, a spirally-shaped second thermoelectric element 14 which is disposed alternately with the first thermoelectric element in the spiral axis direction of the first thermoelectric element to form a double-spiral structure together with the first thermoelectric element, a first electrode 15 which is provided on one surface of the first thermoelectric element in the spiral axis direction, a second electrode 17 which is provided on the other surface of the first thermoelectric element in the spiral axis direction, a third electrode 16 which is provided on one surface of the second thermoelectric element in the spiral axis direction and is opposed to the second electrode, a fourth electrode 18 which is provided on the other surface of the second thermoelectric element in the spiral axis direction and is opposed to the first electrode, a first conductor 22 which electrically connects the second electrode and the third electrode, a second conductor 21 which electrically connects the first electrode and the fourth electrode, a first heat flow passage 12 which is provided between the second electrode and the third electrode, and a second heat flow passage 11 which is provided between the first electrode and the fourth electrode.
