PROBLEM TO BE SOLVED: To provide an easily openable sterilized bag capable of reducing the cost by reducing the area of use of a permeable base material formed of nonwoven fabric. SOLUTION: This sterilized bag comprises a first laminate film having a base layer and a heat-bonding resin layer, a second laminate film having a base layer and a heat-bonding resin layer, and the permeable layer. An opening part is formed in the first laminate film, the permeable base material is fitted to cover the opening part, the heat-bonding resin layer of at least the second laminate film of the heat-bonding resin layer is an easily peelable heat-bonding resin layer. The heat-bonding resin layer or the permeable base material of the first laminate film and the easily peelable heat-bonding resin layer of the second laminate film are adhered and sealed to each other in a peelable manner at a heat-bonding part of a peripheral edge.
