Zusammenfassung:PROBLEM TO BE SOLVED: To provide a novel thermoelectric conversion material suitably used for an n-type thermoelectric conversion element having ZT of 0.4 or more in high temperature region of 600°C.SOLUTION: A thermoelectric conversion material is mainly composed of a BaGaAlSi-based clathrate compound, and B is dispersed into the clathrate compound parent phase. The clathrate compound is represented by a chemical formula BaGaAlSiB(7≤a≤9, 7≤b≤15, 1≤c≤8, 28≤d≤31, 0≤e≤1, a+b+c+d+e=54).
