Abstract

The present invention relates to a secondary battery, comprising: an electrode assembly in which an anode plate and a cathode plate are arranged with a separator interposed therebetween; a cap assembly for sealing an open end of a case in which the electrode assembly is accommodated; a gasket interposed between the case and the cap assembly; and a leakage prevention portion formed on a surface of the cap assembly and/or on a surface of the gasket, wherein the surface of the cap assembly is directed toward the electrode assembly and contacts the gasket.
