SOLUTION: The cushioning packaging bag has a large number of demarcated long sealed bags 12 continuous in the transverse direction, the sealed bags 12 filled with air are formed of a cushioning material of a synthetic resin film sheet constituted so as to independently keep the sealed condition, and the sealed bags 12 are folded in the longitudinal direction so as to form the cushioning material in a cylindrical shape. An insertion port of an article 19 to be packaged is formed between ends of the cushioning material in the folding direction, by welding a space between the sealed bags 12-A located on both ends of the large number of arranged sealed bags 12 to the sealed bags 12 located on the inner side of the sealed bags 12-A located on both ends, so as to close openings formed in the sealed bags 12-A located on both ends of a large number of arranged sealed bags 12.
