As the starting materials, lithium sulfide (Li2S) and phosphorus pentasulfide (P2S5) were used. Powders thereof were measured to have a molar ratio of Li2S:P2S5=75:25 so as to be mixed in an agate mortar. Then, 2 g of the mixture was introduced into a 45 ml of zirconia pot, 4 g of dehydrated heptane (moisture content 30 ppm or less) was introduced, and furthermore, a zirconia ball (φ5.5 mm, 53 g) was introduced, and then the pot was completely sealed. With the pot mounted on a planetary type ball mill machine (P7™ produced by Fritsch Japan Co., Ltd.), a mechanical milling operation was carried out for 20 times with a 500 rpm base plate rotational frequency by a one hour process and 15 minutes pause cycle. Furthermore, after adding 6 mol % of Li2O, the mechanical milling was carried out in the same conditions as mentioned above. Thereafter, the obtained specimen was dried on a hot plate set at 100° C. for removing the heptane so as to obtain a sulfide solid electrolyte material (sulfide glass, Li2S—Li2O—P2S5).
