PROBLEM TO BE SOLVED: To provide a discharging gun cartridge which can be manufactured only of a film without molding, and which can prevent deep wrinkles from occurring when the cartridge is crushed by a discharging gun. SOLUTION: The discharging gun cartridge 21 comprises a cylindrical barrel film 22, a base film 23 provided at a rear end (lower end) in an axial line of the barrel film 22 wherein the base film 23 is folded into a chevron shape and the center in a direction where a crease extends expands with contents filled, and a nozzle 24 provided at a front end (upper end) in the axial direction of the barrel film. The barrel film 22 is formed by sticking both ends of a rectangular flat film, wherein a pasted portion 22a where the barrel film 22 is stuck extends from the rear end to the front end in the axial direction of the barrel film 22. The nozzle 24 is manufactured by sealing the front end of the barrel film 22 and cutting the front end.
