PROBLEM TO BE SOLVED: To provide a transparent bag suitable for packaging electronic components, which excels in airtightness, vapor barrier properties, and gas barrier properties, etc. SOLUTION: Two sheets of transparent film, in which polyethylene terephthalate film having an inorganic compound deposition layer, polyamide film, and straight-chain low density polyethylene film are laminated together in that order, are superposed so that the straight-chain low density polyethylene film comes inside. The open end of a bag body whose both sides and one end are fused under heat has two parallel plastic zippers disposed parallel to the open end, each zipper having a pair of teeth, one male and the other female. In such a transparent packaging bag for electronic components, both the opening-side plastic zipper and the contents-side plastic zipper are formed such that a continuous fastening wall is formed inside and parallel to the male teeth, and a continuous pressing rib is formed inside and parallel to the female teeth.
