A secondary battery manufacturing method according to one embodiment of the present document comprises: a first sealing step of sealing the edge of a pouch-type exterior material by forming an edge sealing part on the edge of the pouch-type exterior material having an accommodation part for accommodating an electrode assembly and a collection part for collecting gas generated during a charging/discharging process of the electrode assembly; a degassing step of discharging the gas collected in the collection part during the charging/discharging process of the electrode assembly to the outside of the pouch-type exterior material; and a second sealing step of forming a partition sealing part between the accommodation part and the collection part in the pouch-type exterior material so as to partition the accommodation part from the collection part after the degassing step. The first sealing step may be a step of further forming an additional sealing part which extends in a direction crossing between the accommodation part and the collection part in the edge sealing part and is disposed on the collection part side so as to be spaced apart from the partition sealing part.
