Abstract

A pouch for a secondary battery comprising indentations on a sealing area of the pouch is disclosed. At least some of the indentations are filled with the resin layers of the pouch. A secondary battery comprising the pouch, and an apparatus for sealing the pouch are also provided. The indentations in the pouch can take the shape of dots or lines, and prevent the resin layers of the pouch from leaking out of the pouch during heating and pressing of the sealing area of the pouch. Also, when the resin layers collect in the indentations, forming adhesive cores, reliability of the pouch seal is improved despite a reduction in the sealing area of the pouch.
