PROBLEM TO BE SOLVED: To provide a highly air-permeable fibrous active carbon knit of high tear strength, high in adsorptive performance for organic solvent vapor per unit area and having high gas-barrier property even in case of being wetted with water or sweat. SOLUTION: The fibrous active carbon knit A is obtained by activation carbonizing a fibrous polymer precursor. This fibrous active carbon knit A has the following characteristics: toluene adsorptive performance index is≥25 g/m<SP>2</SP>; air permeability is≥250 cm<SP>3</SP>/cm<SP>2</SP>.s; tear strength is≥2.5 N; and water repellency in accordance with JIS L1092 6.2 is≥2; also, bone dry mass is 80-250 g/m<SP>2</SP>; BET specific surface area is 1,000-3,000 m<SP>2</SP>/g; and knit design represents rib stitch or interlock stitch.
