PROBLEM TO BE SOLVED: To provide a heat exchanger and a thermoelectric generator capable of suppressing change of fin intervals due to thermal deformation of fins. SOLUTION: A high temperature side heat exchanger 12 constructing an exhaust thermoelectric generator 10 is provided with a high temperature side heat exchanger case 18 forming a passage of exhaust gas and a fin heat collection part 20 having a plurality of fins 48 arranged in parallel with an exhaust gas flow direction in a high temperature side heat exchanger case 18. At least part of an outer surface of a circumference wall of the high temperature side heat exchanger case 18 is used as an upper side heat transmission surface 12A and a lower side heat transmission surface 12B touching each heat power generation module 16. A plurality of heat collection fin 48 is formed in a corrugated plate shape to make thermal deformation direction consistent. COPYRIGHT: (C)2007,JPO&INPIT
