    Thermoelectric properties of Chevrel-type sulfides AMo_6S_8 (A=Fe, Ni, Ag, Zn, Sn, Pb, Cu) were investigated with respect to many advantageous characteristics of the Chevrel compounds for thermoelectric applications. The electrical conductivity, σ, was 10^2.5S・cm^<-1><10^3S・cm^<-1> for most of the samples from room temporature to 1000℃; AgMo_6S_8 gave the largest σ up to 250℃. The Seebeck coefficient, S, was positive for all the samples, indicating the p-type conduction. All the S values were 10μV・K^<-1><S<80μV・K^<-1>and AgMo_6S_8 showed smallest S, probably owing to the higher hole concentration for A=Ag compared to other samples. The maximum S^2σ value was attained by SnMo_6S_8, reaching ca. 1.7×10^<-4> W・m^<-1.>K^<-2> at 800℃. All the k values were 1 W・m^<-1.>K^<-1><κ<3W・m^<-1.>K^<-1> from room temperature to 1000℃. The maximum Z value was ca. 0.07×10^<-3>K^<-1> attained by SnMo_6S_8 at 800℃.
