PROBLEM TO BE SOLVED: To provide a bag body having an exhausting structure capable of discharging unnecessary gas or liquid in the bag body when sealing a commodity in the bag body, preventing the commodity in the bag body from being discharged outside, and also preventing extremely fine powder or the like from being discharged outside. SOLUTION: A nonwoven fabric is held between surface and back films and bonded to one ridge part of a bag body, and a conduction passage to be communicated with the outside from the inside is provided. The nonwoven fabric is folded into two, and held between the films, and the folded part is not bonded inside the bag body but projected therefrom. An in-bag passage of a non-bonded part is formed between the inner side of the part and a bonded part of the bag body, which is communicated with the conduction passage to discharge the gas and the liquid inside the bag body outside from the inside of the bag body.
