PROBLEM TO BE SOLVED: To provide a sintered compact of a compound represented by chemical formulaβ-(Zn1-x Cdx )4 Sb3 in which residual stress is decreased and no crack is present and mechanical strength is increased and also to provide its manufacturing method. SOLUTION: The sintered compact of a compound represented by chemical formulaβ-(Zn1-x Cdx )4 Sb3 can be obtained by preparing powder for forming a compound made up of a combination of Zn, Cd and Sb components in a proportion represented byβ-(Zn1-x Cdx )4 Sb3 (where the symbol x is 0 to 0.3, excluding 0) by mole ratio, vacuum-sealing the powder, performing melting at about 650 to 700 deg.C and solidification, crushing the resultant compound, successively maintaining the compound under the prescribed conditions of 50 to 100 MPa pressure and 400 to 500 deg.C sintering temperature to carry out densification treatment and then releasing, after the completion of the treatment, the above pressure by the time the temperature reaches 95% of the sintering temperature. Its manufacturing method can also be provided.
