Claim Text:
1. A method for generating electricity by using a thermoelectric material having a Heusler alloy type crystal structure and having a structure expressed by General Formula Fe 2 V 1−Z Al 1+z , the structure based on an Fe 2 VAl basic structure having a total number of valence electrons of 24 per chemical formula, wherein z satisfies a condition expressed by 0.03≦z≦0.12; wherein the thermoelectric material is controlled to have a total number of valence electrons of 23.76 or more and less than 24 per chemical formula and to act as a p-type material; and wherein the thermoelectric material has a Seebeck coefficient whose absolute value reaches a peak at a temperature of 400 K or higher, and the Seebeck coefficient has an absolute value of about 50 μV/K or more at temperatures from 500 K to 700 K, and electricity is generated by using the thermoelectric material at a temperature in a range from 500K to 700K.
