A lithium secondary battery is provided to improve shear strength of a hot melting part including a protection circuit board by simplifying the shape of a lead plate. A lithium secondary battery includes an electrode assembly, a can for accommodating the electrode assembly, and a cap assembly which comprises a cap plate(240) and seals a top opening of the can. A hot melting part including a protection circuit board is formed on the cap plate. An intaglio anchor(245) is formed on the one side of the cap plate. A support member(248) is inserted into the intaglio anchor. The cap plate has a terminal through hole(241) for a first electrode terminal in the center. An electrolyte inlet(242) is formed on the one side and a safety vent(243) is formed on the other side on the basis of the terminal through hole. |
