PROBLEM TO BE SOLVED: To provide a fibrous activated carbon sheet prevented from the falling- off and scattering of dust of activated carbon generated by the damage or powdering of fibers caused by the mechanical force applied to the fibrous activated carbon sheet, excellent not only in air permeability and flexibility but also in the water/oil repellency of a material surface inclusive of perforation parts due to quilting. SOLUTION: A quilting laminated fabric, wherein fibrous activated carbon cloth is held between base materials (adsorbing material protective layers) excellent in air permeability and flexibility, is subjected to immersion treatment (dipping nipping treatment) in a binder resin processing bath of an aqueous dispersion system together using a water repellent and the treated fabric is subjected to drying and fixing treatment (drying curing treatment) to obtain the quilting sheet.
