Abstract

A lithium secondary battery includes an electricity generating portion in which positive electrode 60 and negative electrode 61 form a laminate through separator films 62 made of porous polymer so that the positive electrode 60 and the negative electrode 61 do not come in direct contact with each other, leads 65, 77 which are respectively connected to plural portions of the positive electrode 60 and the negative electrode 61 to make electricity collection, and a low melting point alloy member 76 as a current break mechanism being inserted in a current path of the inside of the battery, which is melted to break the current path when the temperature of the battery is raised over a predetermined temperature.
