The secondary battery may include an electrode assembly to which an electrode lead is attached, a battery case including an accommodation portion to receive the electrode assembly therein such that a portion of the electrode lead may extend outside the battery case, a lead film disposed around an outer surface of the electrode lead, and a vent member. The battery case may include a sealing portion containing a sealant resin to form a seal at least partially around the electrode assembly. The lead film may be interposed between the electrode lead and the sealing portion. The vent member may contain a vent resin having a lower melting point than the sealant resin. The vent member may at least partially overlap or contact the lead film.",
