摘要： The present disclosure relates to a method for sealing a pouch casing of a pouch-type secondary battery, which includes the steps of: a receiving step in which an electrode assembly is received in an inner space formed between an upper pouch and a lower pouch; and a sealing step in which a first pressure is applied to an outer circumferential sealing portion, where the upper pouch and the lower pouch are sealed, in the longitudinal direction, and then the pressure is relieved, wherein the sealing step is carried out by applying external force to the upper pouch in the upward direction and to the lower pouch in the downward direction, or by applying a second pressure working in perpendicular to the first pressure to the sealing portion from the inner part of the pouch casing in a direction toward the outside.
