PROBLEM TO BE SOLVED: To make a thermal energy generated at a Peltier element uniform in a thermoelectric cooling module for controlling a temperature used for a humidity detecting sensor or the like. SOLUTION: The thermoelectric cooling module 1 comprises a plurality of the Peltier elements 2, copper plates 4 arranged on one end faces and other end faces of these elements 2 via solders 3, and first and second substrates 5, 6 fixed to the respective end face sides to control the temperature. In the module 1, heights of the elements 2 between the substrates 5 and 6 are lower at those disposed at an outside than those disposed at a central part of the substrates 5, 6, in such a manner that a difference is supplemented (absorbed) by a thickness of the solder 3 between the elements 2 and the plate 4 disposed between the substrates 5 and 6.
