A cell content container (10) is provided with an inner bag (12) and an outer bag (16). The inner bag (12) is a bag the peripheral edge of which is sealed except for an opening (14). The outer bag (16) is a bag the peripheral edge of which is sealed except for an opening (24), and contains the inner bag (12) with the opening (14) facing outward. A portion, in which the inner bag (12) is not present, of the opening (24) is sealed by an outer bag sealing portion (28). Further, a portion, in which the inner bag (12) is present, of the opening (24) is sealed by an inter-bag sealing portion (18). A space surrounded by the outer surface of the inner bag (12) and the inner surface of the outer bag (16) is a closed space (20) subjected to sterilization treatment. A material for the inner bag (12) and a material for the outer bag (16) are selected such that adhesive strength when the inner surfaces of the opening (14) of the inner bag (12) are thermally welded becomes stronger than the adhesive strengths of the inter-bag sealing portion (18) and an outer bag sealing portion (28). |
