PROBLEM TO BE SOLVED: To provide a thermoelectric conversion module capable of securing the flatness of top and bottom faces even when a tube body for a compressive fluid to flow has a reduced wall thickness.SOLUTION: The thermoelectric conversion module comprises: a cylindrical tube body 11 used for a compressive fluid to flow; a high temperature side electrode part disposed on each of the top face and the bottom face sides of the tube body and electrically insulated from the tube body; a thermoelectric conversion element disposed on the high temperature side electrode part; a low temperature side electrode part disposed on the thermoelectric conversion element; and a case member 15 for accommodating the tube body, the high temperature side electrode part, the thermoelectric conversion element, and the low temperature side electrode part. The thermoelectric conversion module is configured in such a way that, in a non-formation region of the thermoelectric conversion element in a direction almost perpendicular to the passage direction of the compressive fluid, the upper tube wall and/or the lower tube wall of the tube body has a depressed rib 23 formed so as to touch the upper tube wall and/or the lower tube wall of the tube body, and that the high temperature side electrode part and/or the low temperature side electrode part include a bridge-shaped electrode 25 formed so as to stretch over a recess which is formed as a result of the rib. |
