  "textContent": "The present invention relates to an apparatus for manufacturing a pouch of a secondary battery and a pouch of a secondary battery, which is manufactured by the apparatus, and more particularly, to an apparatus for manufacturing a pouch of a secondary battery, in which, when the pouch having two cup parts is molded, the pouch is molded by relieving a pressure applied to a pouch bridge that is a narrow connection part between the two cup parts to improve quality of a finally molded pouch product, and a pouch of a secondary battery manufactured by the method. [0002] An apparatus for manufacturing a pouch of a secondary battery includes: a lower die having an accommodation groove for molding a cup part of the pouch in a base surface, on which the pouch is disposed; a punch inserted into the accommodation groove of the lower die to mold the cup part of the pouch; and a stripper provided to press a peripheral part of the pouch, which is disposed around a portion to be molded as the cup part of the pouch by the punch, wherein two accommodation grooves provided with a left accommodation groove and a right accommodation groove are formed in the lower die, a bridge part configured to connect the two accommodation grooves to each other is formed between the left accommodation groove and the right accommodation groove, the bridge part includes a pillar portion of which lateral sides are formed as two straight lines and a top portion formed as a curve on an upper end of the pillar portion, based on a cross-sectional view, and a height (h) of the top portion, which is measured at an upper end of the pillar portion, is less than 1/2 of a width (W) of the pillar portion.",
