摘 要：
<P>PROBLEM TO BE SOLVED: To provide a secondary battery improved in sealing performance by preventing leakage of a gas generated from the inside of the battery or an electrolyte by forming raised projections or incised
grooves on a surface of a gasket in a part in contact with a safety vent or a surface of the gasket in a part in contact with a bead. <P>SOLUTION: This lithium secondary battery includes: an electrode assembly; a vessel type can for receiving the electrode assembly therein; a cap assembly provided with the safety vent having a projecting part projecting from the center to a lower part and deformed to an upper part by internal pressure of the battery, a current cutoff means, and a cap-up connected to an upper part of the current cutoff means and used for sealing an opening of the can; and the gasket
