摘要：
A thermoelectric conversion material includes: a base material that is a semiconductor composed of a base material element; a first additional element that is an element different from the base material element, has a vacant orbital in a d orbital or f orbital located internal to an outermost shell of the first additional element and forms a first additional level in a forbidden band of the base material; and a second additional element that is an element different from both of the base material element and the first additional element and forms a second additional level in the forbidden band of the base material. A difference is 1 between the number of electrons in an outermost shell of the second additional element and the number of electrons in at least one outermost shell of the base material element.
