To provide a gas and steam permeable absorption filter material which has protective functions against living organism and chemical harmful substances, and toxic substances, especially against living organism and chemical weapons.

This adsorption filter material comprises a sheet-like first carrier layer 3, a sheet-like second carrier layer 4, and an adsorption layer 5 inserted between the first carrier layer 3 and the second carrier layer 4, which is made of activated carbon fiber fabric durably stuck to the first carrier layer 3 and the second carrier layer 4 with an adhesive 6. The activated carbon fiber fabric's adhesion to the first carrier layer and the second carrier layer are respectively achieved by intermittently applying the adhesive in dots apart from one another. This adsorption filter material is especially used for manufacturing protective products, especially for protective clothing, protective gloves, protective shoes, other protective clothes, and protective covers.
