PROBLEM TO BE SOLVED: To provide a thermoelectric conversion module in which relaxation of stress and distortion in an element and at a joint is achieved, in the vicinity of the joint of element/high temperature side electrode where stress concentrates.SOLUTION: In a thermoelectric conversion module where the electrodes arranged on the high temperature side and low temperature side, and P type and N type thermoelectric conversion elements are connected via a bonding layer, the bonding area of the P type and N type thermoelectric conversion elements and the high temperature side electrode is smaller than the bonding area of the P type and N type thermoelectric conversion elements and the low temperature side electrode. For that purpose, a notch is formed by removing a portion of the outer periphery of the high temperature side joint of the thermoelectric conversion element, or a portion of the high temperature side electrode facing the outer periphery of the high temperature side joint of the thermoelectric conversion element. |
