PROBLEM TO BE SOLVED: To provide a breathable bag which can be satisfactorily deaerated on filling and hardly allows moisture to come inside even when being wet. SOLUTION: For the breathable bag made up by putting two sheets of square laminated films each having a base layer and a heat-sealable resin layer together with each of the heat-sealable resin layers facing each other and intermittent heat-sealing parts each comprising of heat-sealing parts and non-heat-sealing parts formed respectively at opposite two sides, the intermittent heat-sealing part is formed in a structure wherein at least one layer of nonwoven fabric is inserted between the heat-sealable resin layers of the laminated films, and are heat-sealed the nonwoven fabric and the heat-sealable resin layers and the nonwoven fabrics are mutually heat-sealed as well.
