To provide a bag which requires no mold release tape to cover a pressure-sensitive adhesive layer and a method for manufacturing the same.

An article storage chamber having an upper opening part is formed of surface and back sheet parts, a sealing strip extending over the upper opening part extends from the back sheet part and is freely returnable so as to overlap the outer side of a part in a vicinity of an opening edge of the surface sheet part, and a bag body is sealed by sticking the pressure-sensitive adhesive layer provided on the sealing strip to a bearing strip added to the outer side of the part in a vicinity of the opening edge of the surface sheet part. When the sealing strip is turned back via a first freely foldable part, the pressure-sensitive adhesive layer faces a temporary receiving part of the surface sheet part provided at the position where the adhesive layer is deviated downwardly or upwardly from the bearing strip. When the sealing strip is turned back via a second freely foldable part, the adhesive layer faces the bearing strip. The temporary receiving part of the surface sheet part forms a easily peelable part to peelably stick the adhesive layer of the sealing strip. The easily peelable part is formed of a mesh-net material.
