Abstract: The present disclosure provides a thermoelectric conversion material having a composition represented by a chemical formula of Li2−a+bMg1−bSi. In this thermoelectric conversion material, either requirement (i) in which 0≤a≤0.0001 and 0.0001≤b≤0.25-a or requirement (ii) in which 0.0001≤a≤0.25 and 0≤b≤0.25-a is satisfied. The thermoelectric conversion material has an Li8Al3Si5 type crystalline structure.
