Claim 4:
5. A manufacturing method of the thermoelectric material according to claim 1, the method comprising:
melting and casting an alloy which is a raw material of a sintered body of the thermoelectric material by a high frequency vacuum melting method to produce an ingot,
pulverizing the ingot to obtain powder particles,
sintering the powder particles by a sintering method without using a binder to form a sintered body of crystal particles, and
processing the sintered body into a predetermined shape by machining process in which no stress equal to or higher than a yield stress of the sintered body is applied to the sintered body during the processing of the sintered body.
