摘要：
A thermoelectric conversion material includes: a base material that is a semiconductor; and an additive element that differs from an element constituting the base material. An additional band formed of the additive element is present within a forbidden band of the base material. A density of states of the additional band has a ratio of greater than or equal to 0.1 relative to a maximum value of a density of states of a valence band adjacent to the forbidden band of the base material.
