A solid electrolyte and a method of manufacturing the same are provided. Th e solid electrolyte contains x atomic % of lithium, y atomic % of phosphorus, z atomic % of sulfur, and w atomic % of oxygen, in which the x, the y, the z, and the w satisfy the following expressions (1)-(5): 20.ltoreq.x.ltoreq. 45 ...(1) 10.ltoreq.y.ltoreq.20 ...(2) 35.ltoreq.z.ltoreq. 60 ...(3) 1.ltoreq.w.ltoreq.10 ...(4) x + y + z + w = 100 ...(5), and apexes of X-ray diffraction peaks in an X-ray diffraction pattern obtained b y an X-ray diffraction method using a K.alpha.-ray of Cu exist at diffraction angles 2.theta. of 16.7.degree.~ 0.25.degree., 20.4.degree.~0.25.degree., 23.8.degree.~0.25.degree., 25.9.degree.~0.25.degree., 29.4.degree.~ 0.25.degree., 30.4.degree.~0.25.degree., 31.7.degree.~ 0.25.degree., 33.5.degree.~0.25.degree., 41.5.degree.~0.25.degree., 43.7.degree.~0.25.degree., and 51.2.degree.~0.25.degree., respectively, in the X-ray diffraction pattern, and a half-width of each of the X-ray diffraction peaks is not larger than 0.5.degree.. |
