A food packaging container and a packaging method are provided which ensure convenient use of the container when and after an outer bag is opened. An individual wrapping sheet (2) for individually wrapping a chewing gum piece (1) is dividable into a separation portion (2A) and a fixing portion (2B) longitudinally of the chewing gum piece (1). A plurality of individually wrapped chewing gum pieces (1) (food units (3)) are aligned side by side on a rear outer packaging material (51), and a front outer packaging material (52) is folded along one edge (53) of the rear outer packaging material (51) to cover upper surfaces of the food units (3). The rear outer packaging material (51) and the front outer packaging material (52) are combined with each other with their peripheral edge portions sealed with a seal portion (7). A packaging container (100) (outer bag) is completed with the rear outer packaging material (51) and the front outer packaging material (52) thus combined, whereby the food units (3) are sealingly enclosed in the packaging container (100). The fixing portions (2B) of the individual wrapping sheets (2) of the respective food units (3) are fixed to at least one of the rear outer packaging material (51) and the front outer packaging material (52) via an adhesive member (8).
