摘要：
A thermoelectric conversion material includes a base material that is a semiconductor having Si and Ge as constituent elements, a first additive element that is different from the constituent elements, has a vacant orbital in a d or f orbital located inside an outermost shell thereof, and forms a first additional level in a forbidden band of the base material, and oxygen. The oxygen content ratio is 6 at % or less.
