PROBLEM TO BE SOLVED: To provide an interior bag for a bag-in-box capable of storing contents which are relatively highly viscous and easily solidified by oxidation when discharged. SOLUTION: In the interior bag for the bag-in-box, a first storage part (11) is formed between an inner film and an intermediate film by heat-sealing a peripheral edge of a film consisting of an inner film (1), an intermediate film (2) and an outer film (3) overlapping each other in three layers, and a second storage part (12) is formed between the intermediate film and the outer film, respectively. A filling/discharging hole (13) to penetrate the first storage part and the outside is formed in the inner film of the interior bag, and a gas filling/exhausting hole (14) to penetrate the second storage part and the outside is formed in the outer film of the interior bag. A fluid passage plate (15) with a projecting bar (16) formed in a corrugated manner on one side is fitted to the intermediate film side of the first storage part with the projection forming face in contact with the content side.
