| description | To provide an n-type thermoelectric conversion material having an excellent thermoelectric conversion performance.SOLUTION: In an n-type thermoelectric conversion material of the present invention, a sulfide having an n-type thermoelectric conversion characteristic is included as a base material, and it is expressed by (a) a composition where, in a composition formula expressing an element ratio of the base material, the ratio of at least one base material structure element excluding sulfur is reduced, and the ratio of a typical metal element (however, the base material construction element is excluded) is increased by the substantially same amount of the ratio to be reduced, and/or (b) a composition where, in the composition formula expressing the element ratio of the base material, the ratio of at least one base material structure element excluding sulfur is reduced, and the ratio of the typical metal element (however, the base material structure element is excluded) is increased so as to maintain a crystal electrical neutrality of the base material. The n-type thermoelectric conversion material contains 3 mol% or more of the typical metal element in full of a sulfide composition.SELECTED DRAWING: None
