ABSTRACT:
To provide a thermoelectric conversion material having semiconductor-like temperature dependence, that is, the property that electric resistivity decreases with increasing temperature, and having high thermoelectric performance. The present invention is a thermoelectric conversion material including a semiconductor phase having a layered bronze structure expressed by a formula of Ay(Co1-xRhx)O2, where A is an alkaline-earth metal, y is 0.2 to 0.8, and x is 0.4 to 0.6.
