Glass particles including Li, P and S, wherein when a Raman spectrum of the glass particles is measured five times or more and a peak at 330 to 450 cm -1 in the Raman spectrum is separated into peaks of components by waveform separation, the standard deviation of the area ratio of each of the peaks of the components is 3.0 or less, the area of the peak of PS 4 3- component obtained by the waveform separation is 10 to 95% of the total area, and the area of P 2 S 7 4- component obtained by the waveform separation is 5 to 45% of the total area, and the area of the peak of PS 4 3- component is larger than the area of the peak of P 2 S 7 4- component. |
