A packaging bag is a packaging bag made of a laminate formed in a bag shape which is in a rectangular shape in plan view, the laminate being composed of a sheet-shaped substrate made of a resin, a cushioning material made of a foamed resin sheet laminated on an inner side relative to the substrate, and a sealant layer laminated on an inner side relative to the cushioning material. The packaging bag includes a seal section in which the sealant layers are sealed to each other on one end edge in a flow direction (MD direction) of the foamed resin sheet, the seal section extending in a direction perpendicular to the flow direction of the foamed resin sheet, wherein a notch is formed in the seal section to be oriented to the other end edge in the flow direction of the foamed resin sheet.
