Abstract
Provided is a thermoelectric conversion material formed from a full Heusler alloy represented by the composition formula: Fe(TiM1)(AlM2). M1 represents at least one element selected from the group consisting of V, Nb and Ta, and M2 represents at least one element selected from the group consisting of Group 13 elements except for Al and Group 14 elements. α satisfies the relation: 0<α≤0.42, β satisfies the relation: 0≤β<0.75, and δ satisfies the relation: 0≤δ<0.5. The valence electron concentration, VEC, satisfies the relation: 5.91≤VEC<6.16.
