The assignment of the present invention is to provide an adsorbing film which is suitable for a buffer which will be installed in an adsorbing plate such as a mold and the likes when adsorbing a plate shaped adsorbed material which is easy to be deformed such as a ceramic green sheet. Coating a release film (1) with heated hot melt adhesive; welding the adhesive to a porous sheet (3) when the adhesive becomes low temperature; forming a laminated body in which the release film (1), an adhesive layer (2) which is composed of the hot melt adhesive, and the porous sheet (3) are laminated in order; and exfoliating the release film (1) from the laminated body and obtaining the adsorbing film which is formed by laminating the adhesive layer (2) and the porous sheet (3). The porous sheet is called ultrahigh molecular weight polyethylene resin porous sheet. The adsorbing film has 0.8 N/25 mm or more of stainless adhesion and 5 cm^3/cm^2·second or more of permeability for the adhesive layer. |
