Abstract
Provided is a non-aqueous electrolyte secondary battery capable of reliably operating an electricity shut-off mechanism at overcharging without deteriorating battery performance. The non-aqueous electrolyte secondary battery () includes, in a container (): a positive electrode (); in-container positive electrode terminals () and (); a negative electrode (); in-container negative electrode terminals () and (); a non-aqueous electrolyte solution; and an electricity shut-off mechanism () capable of shutting off energization with the outside of the container when the internal pressure of the container rises. A solid electrolyte layer that produces gas allowing the electricity shut-off mechanism () to be operated is included in at least one member of a positive electrode mixture layer unformed portion (), a negative electrode mixture layer unformed portion (), the in-container positive electrode terminals () and (), and the in-container negative electrode terminals () and ().
