PROBLEM TO BE SOLVED: To provide a manufacturing method for efficiently manufacturing a bag in such a way that an internal partitioning is formed when the bag is formed. SOLUTION: According to the method for manufacturing the bag 1, a bag forming pasteboard has a plurality of side wall forming portions 11 to 16 for forming the side walls of the bag 1 and a plurality of bottom forming portions for forming the bottom part 4 of the bag 1, and each side wall forming portion and each bottom forming portion are folded and are joined at a specified position to form the bag 1 having a storage space inside thereof. The bag forming pasteboard also includes a partitioning forming portion for forming a partitioning 5 partitioning the storage space, which partitioning forming portion is formed integrally with the side wall forming portions. When the side wall forming portions are folded to form the side walls of the bag 1, the partitioning forming portion is set between the side walls to form the partitioning 5 partitioning the storage space of the bag 1.
