Abstract
A lithium secondary battery contains an electrode body obtained by winding a positive electrode and a negative electrode via a separator, a non-aqueous electrolytic solution, and a battery case accommodating the electrode body and the non-aqueous electrolytic solution. A lid and a metal foil are adhered to each other with a resin to form a pressure-releasing valve and make air-tight the inside of the battery case. This secondary battery is easy to produce and has excellent operational safety and excellent reliability.
