Zusammenfassung:	The present invention relates to a secondary battery pouch which can minimize the folded region of the bridge portion of a pouch produced by folding two receiving portions, and a mold die for molding the secondary battery pouch. In addition, the secondary battery pouch includes a lower receiving portion for receiving an electrode assembly, an upper receiving portion for blocking the opening of the lower receiving portion; and a bridge portion for connecting the lower receiving portion and the upper receiving portion. When the lower receiving portion and the upper receiving portion are developed, the height of the bridge portion measured from the bottom of the lower receiving portion is lower than the height of the lower receiving portion measured from the bottom of the lower receiving portion. 본 발명은 두 개의 수용부를 포개지게 접어 제작하는 파우치의 브릿지부 접힘 영역을 최소화할 수 있는 이차전지용 파우치 및 그 이차전지용 파우치를 성형하기 위한 금형 다이에 관한 것이다. 또한, 본 발명은 전극조립체를 내부에 수용하는 하부 수용부, 상기 하부 수용부의 개구를 막는 상부 수용부 및 상기 하부 수용부와 상기 상부 수용부를 연결하는 브릿지부를 포함하고, 상기 하부 수용부와 상기 상부 수용부를 전개하였을 때, 상기 하부 수용부의 저면으로부터 측정한 상기 브릿지부의 높이는 상기 하부 수용부의 저면으로부터 측정한 상기 하부 수용부의 높이보다 낮은 것을 특징으로 한다.
