PROBLEM TO BE SOLVED: To provide a thermoelectric material excellent in thermoelectric performance, processability, and strength. SOLUTION: Aluminum borate (9Al<SB>2</SB>O<SB>3</SB>2B<SB>2</SB>O<SB>3</SB>) whisker as reinforcing fiber in the range of 3-10 vol.% is mixed with a thermoelectric material powder to evenly disperse the reinforcing fiber, and then press molded and sintered to produce the thermoelectric material having a filling factor≥80%. Thus, produced thermoelectric material is excellent in thermoelectric performance and processability, and the strength thereof can be improved because it contains aluminum borate (9Al<SB>2</SB>O<SB>3</SB>2B<SB>2</SB>O<SB>3</SB>) whisker for improving the strength thereof.
