A safe and highly-reliable all-solid-state lithium secondary battery using a sulfide-based solid electrolyte material which can restrain generation of hydrogen sulfide gas, in case a large amount of water is entered into a battery case by an accident such as submersion associated with a breakage of the container. An all-solid-state lithium secondary battery using a sulfide-based solid electrolyte material, wherein the battery has a metal salt M-X comprising a metal element “M” and an anionic part “X” in a battery case thereof, and further wherein a metal cation of the metal salt M-X generated by disassociation caused with water can react with a sulfide ion generated by a reaction between the sulfide-based solid electrolyte material and the water. |
