Abstract

Provided are a pouch for a secondary battery, which is capable of minimizing a folded area of a bridge part of the pouch that is manufactured by folding two accommodation parts to overlap each other, and a die for forming the pouch for the secondary battery. The pouch for the secondary battery includes a lower accommodation part accommodating an electrode assembly therein, an upper accommodation part covering an opening of the lower accommodation part, and a bridge part connecting the lower accommodation part to the upper accommodation part. When the lower accommodation part and the upper accommodation part are unfolded, a height of the bridge part, which is measured from a bottom surface of the lower accommodation part, is lower than that of the lower accommodation part, which is measured from the bottom surface of the lower accommodation part.
