PROBLEM TO BE SOLVED: To provide a thermoelectric power generation module which can keep appropriate power generation performance for a long time even under severe application condition where a heat collector on the high-temerpature side becomes higher. SOLUTION: When a heat collecting substrate 1 becomes higher in temperature while it is being used, an electrode plate 5 and the high-temperature ends of respective thermoelectric power generation elements N and P are got in contact with each other flexibly and appropriately by means of a melted low-melting-point metal layer 8A. As a result, appropriate thermal and electric conduction is realized between the heat collecting substrate 1 and the high-temperature ends of the respective thermoelectric power generation elements N and P, and the generation of thermal stress between the electrode plate 5 and the high-temperature ends of the respective thermoelectric power generation elements N and P can be prevented in advance. In addition, an insulator 9 blocks in advance the recondensation of vapor on the circumferential surface of the thermoelectric power generation elements N and P that is generated from melted low-melting-point metal layers 8A and 8B, thereby keeping appropriate insulation on the circumferential surface of the thermoelectric power generation elements N and P.
