A nitrogen-containing thermoelectric material, which has an element composition represented by: <?in-line-formulae description="In-line Formulae" end="lead"?>AlzGayInxMuRvOsNt (A)<?in-line-formulae description="In-line Formulae" end="tail"?> <?in-line-formulae description="In-line Formulae" end="lead"?>or<?in-line-formulae description="In-line Formulae" end="tail"?> <?in-line-formulae description="In-line Formulae" end="lead"?>AlzGayInxMuRvDwNm (B)<?in-line-formulae description="In-line Formulae" end="tail"?> (wherein M represents a transition element; R represents a rare earth element; D represents at least one element selected from elements of the Group IV or II; 0<=z<=0.7, 0<=y<=0.7, 0.2<=x<=1.0, 0<=u<=0.7, 0<=v<=0.05, 0.9<=s+t<=1.7, 0.4<=s<=1.2, 0<=w<=0.2, and 0.9<=m<=1.1; and x+y+z=1), and has an absolute value of a Seebeck coefficient of 40 muV/K or more at a temperature of 100° C. or more. These thermoelectric materials comprise elements having low toxicity, are excellent in a heat resistance, a chemical resistance and the like, and have a high thermoelectric transforming efficiency.
