PROBLEM TO BE SOLVED: To provide a thermoelectric module which can improve strength, increase humidity resistance and also enhance operational reliability. SOLUTION: In the module, P type thermoelectric elements 3a and N type thermoelectric elements 3b are disposed as adjacent to each other, both the upper and lower sides of the elements 3 are connected to respective conductive electrodes 4, and heat exchange substrates 5 are fixed to the both electrodes 4. The elements 3 are coated with films 3 of an insulating material, except for their faces joined to the electrodes 4, and the adjacent elements 3 are spaced from each other. The formation of the films 2 of the insulating material reinforces strengths of the elements 3 and prevents crackings and missing of the elements 3 by suppressing destruction of the elements 3 caused by thermal stresses, when subjected to weight or shocks. The module 1 can prevent corrosion of the elements 3 in high humidity atmosphere and can improve its operational reliability by improving the humidity resistance of the element 3. |
