PROBLEM TO BE SOLVED: To provide a durable Peltier module where, even if a junction part between a P- or N-type thermoelectric element and a junction electrode or a P- or N-type thermoelectric element is repeatedly applied with a thermal stress, such failure as disconnection caused by cracking of the junction part or the P- or the N-type thermoelectric element is hard to occur. SOLUTION: An array pattern has an angular part at its periphery which comprises junction electrodes 4 and 4' provided to a pair of substrates 1. A periphery supporting member 5 of a material different from that of a P-type thermoelectric element 2 or an N-type thermoelectric element 3 is provided on the peripheral side of facing angular part junction electrodes 4A and 4'A to form the angular part. The periphery supporting member 5 is jointed to the facing angular-part junction electrodes 4A and 4'A.
