Abstract

Provided is a thermoelectric conversion module including a thermoelectric conversion material layer that has high thermoelectric performance, the thermoelectric conversion material layer containing a thermoelectric conversion material with its electrical resistivity reduced. The thermoelectric conversion module includes the thermoelectric conversion material layer including the thermoelectric conversion material containing at least thermoelectric semiconductor particles. The thermoelectric conversion material layer has voids, and when a proportion of the area occupied by the thermoelectric conversion material within the area of a longitudinal cross-section that includes the center portion of the thermoelectric conversion material layer is defined as a filling ratio, the filling ratio is greater than 0.900 and less than 1.000.
