PROBLEM TO BE SOLVED: To provide a food storage bag inexpensively manufacturable, capable of surely discharging internal gas, and preventing a flavoring ingredient from being lost due to communication with open air. SOLUTION: In the storage bag capable of storing and hermetically sealing food, a film forming the bag is a laminate film composed of an internal film and an external film bonded to each other. A vent enabling air to flow is formed between the internal and external films by leaving a partially unbonded part. A vent pore capable of venting through the inside of the storage bag is formed on the internal film in the vent, and a discharge port capable of communicating with the open air is formed on the external film. When the food discharges gas in the storage bag, the gas is emitted from the discharge port 5 via the vent 4 through the vent pore 6 of the internal film 12, so that internal pressure does not rise and the storage bag does not expand.
