An all-solid lithium secondary battery filled with sulfide base solid electrolyte material that when a large quantity of water penetrates in a battery case by submersion under water accompanying the breakage of container, etc., inhibits any generation of hydrogen sulfide gas, ensuring safety and high reliability. The all-solid lithium secondary battery filled with sulfide base solid electrolyte material is one having metal salt M-X consisting of metal element M and anion moiety X in a battery case, characterized in that the metal cation produced through dissociation of the metal salt M-X by water is capable of reacting with sulfide ion produced by reaction between the sulfide base solid electrolyte material and water. |
