Abstract:
Provided is an all-solid-state secondary battery that has a battery element member including at least one battery unit in which at least a negative electrode active material layer, a solid electrolyte layer, and a positive electrode active material layer are laminated in the stated order. The all-solid-state secondary batter has, at an end of the battery element member, an insulating covering body that covers at least a side surface of the battery element member and that is formed by a mixture of a resin material which melts in a temperature region of 300°C or less and insulating inorganic particles which do not melt at 350°C. Also provided is an all-solid-state secondary battery production method including: a step for disposing, at the end of the battery element member, the mixture of the resin material which melts in the temperature region of 300°C or less and the insulating inorganic particles which do not melt at 350°C; and a step for, while heating the mixture at a temperature at which the resin material melts, applying pressure to the mixture in an inward direction of the battery element member.
