Abstract

본 발명은 내부 공간이 형성된 수용부, 상기 수용부의 개구된 부분을 폐쇄하는 덮개부가 일체로 형성된 파우치 및 파우치형 이차전지에 관한 것으로, 상기 수용부와 덮개부의 경계면 주위에는 절곡연장부가 형성되는 것을 특징으로 한다. 본 발명에 의하면, 수용부와 덮개부가 일체로 형성된 파우치에서, 파우치의 조립시 덮개부를 절곡한 후 수용부와의 접촉면을 실링 처리함으로써 내부를 밀폐하게 되는데, 이때 수용부와 덮개부의 경계면 주위에 절곡연장부를 더 구비하고 이를 실링함으로써 파우치가 밀봉된 이후 상기 경계면을 통해 외부의 수분이 침투하는 것을 최소화할 수 있다.
