At least 80 where it is entwined in the independent non- woven web and the web of the polymer fiber weight % the sorption medicine particle and, being the porous seat goods which are included, the above-mentioned fiber, the elasticity which is sufficiently higher than the polypropylene fiber of similar diameter, or has sufficiently large crystallization contraction, in order for the above-mentioned web at least to have the adsorption factor A of 1.6 104 /mm waters, the sorption medicine particle disperses in the web sufficiently uniformly, the porous seat goods. The adsorption factor to which as for these goods, pressure decrease is small, is higher than the filling up carbon floor the adsorption factor which is close to the filling up carbon floor, with when with these goods, long useful life and, it is possible to offer the filter element which it possesses.ポリマー繊維の自立不織ウェブと、ウェブ中に絡まった少なくとも80重量%の収着剤粒子と、を含む多孔質シート物品であって、上記繊維が、同様の直径のポリプロピレン繊維よりも、十分高い弾性または十分大きい結晶化収縮を有し、上記ウェブが少なくとも1.6×104/mm水の吸着係数Aを有するように、収着剤粒子がウェブ中に十分均一に分散している、多孔質シート物品。この物品は、圧力低下が小さく、この物品によって、長い耐用寿命と、充填炭素床に近い吸着係数、場合により充填炭素床よりも高い吸着係数と、を有するフィルターエレメントを提供することができる。
