Zusammenfassung:	In the case of a conventional resealable packaging bag, it is necessary to design the position for providing a projection piece during the manufacture of the bag, limiting the freedom in manufacturing the bag. Further, the capacity of the bag that has been resealed by folding a folded-back portion is reduced. A packaging bag 1 comprises a main bag body 2, and at least a pair of sub-bag bodies 3 and 4 which are integrally connected to the main bag body 2 and branch into two from the main bag body 2, wherein an opening 6 for rupturing and unsealing is provided close to the tip of at least one sub-bag body. The opening 6 is easily resealable by folding a root part 8 of the sub-bag body having the opening 6 formed therein by rupturing back toward the main bag.
