PROBLEM TO BE SOLVED: To provide a heat exchanger efficiently performing heat exchange by enabling an electrode of a thermoelectric module to directly contact with a fluid for performing heat exchange in a simple structure. SOLUTION: The heat exchanger includes a thermoelectric module 11 in which a plurality of P-type thermoelectric semiconductor devices 16 and a plurality of N-type thermoelectric semiconductor devices 17 are serially connected via electrodes 18, 19 and are disposed thermally in parallel. The heat dissipation side of the thermoelectric module 11 is provided with a first fluid path 13, while the heat absorption side thereof is provided with a second fluid path 15. In the thermoelectric module 11, the thermoelectric semiconductor devices 16, 17 are bonded by an electric insulator 21 made of resin such that the electrodes 18, 19 are exposed in the first fluid path 13 and second fluid path 15, respectively, and the movement of fluids between the both fluid paths 13, 15 can be blocked. The electrodes 18, 19 are formed of a plain plate. The thermoelectric module 11 is provided with projections and recesses which are formed by causing part of the electric insulators 21 to project further into the both fluid paths 13, 15 than the electrodes 18, 19.
