{sup 29}Si and {sup 31}P MAS-NMR spectra were measured for the Li{sub 2}S-SiS{sub 2}-Li{sub 3}PO{sub 4} glasses. {sup 29}Si MAS-NMR spectra revealed that a large number of silicon atoms in the glasses were coordinated with both sulfur and oxygen atoms. {sup 31}P MAS-NMR spectra showed that some phosphorus atoms were also coordinated with both sulfur and oxygen atoms. Such structural units resulted in the improvement of the conductivity and the glass stability against crystallization by the doping of Li{sub 3}PO{sub 4} to the Li{sub 2}S--SiS{sub 2} glasses.
