Abstract: The present invention relates to a pouch cell which can prevent or reduce ingress of moisture outside a pouch into the pouch via a passage portion through which gas inside the pouch is discharged to the outside. The pouch cell according to the present invention may comprise: an electrode lead which is electrically connected to an electrode assembly accommodated in a pouch and protrudes out of the pouch; a lead film which covers a part of the electrode lead so as to insulate the electrode lead from the pouch and includes a passage portion where a gas moving path is formed if the internal pressure in the pouch is increased to a predetermined pressure or higher; and a pressure member which is disposed outside the pouch and provides a force to the passage portion so as to close the passage portion.
