PROBLEM TO BE SOLVED: To provide an n-type thermoelectric conversion material which is usable in a high-temperature range, inexpensive, and high in performance. SOLUTION: The n-type thermoelectric conversion material which contains metal sulfides, such as zinc sulfide ZnS, lead sulfide PbS, and tin sulfide SnS, is excellent in electrical conductivity, and low in thermal conductivity is obtained.
