Containing the water absortion power resin and the adhesive, the absorption layer which becomes, being the water absorption seat constitution body which possesses the structure which keeps from the upper part and the lower part of the said absorption layer with the nonwoven fabrics, the said absorption layer being divided with by primary absorption layer and secondary absorption layer by the fiber substrate where percentage of void is 91 - 99%, it possesses the structure which becomes, the water absorption seat constitution body which is 0.05 - 2.0 times resins content said water absortion power 100 - 1000g/m2, content ratio of the said adhesive resins content water absortion power (mass standard) vis-a-vis. That the water absorption seat constitution body which depends on this invention, being thin shape, because formal retention characteristic is satisfactory, does not cause type deterioration before the liquid absorbing, and after the absorbing furthermore liquid permeability, can show the absorption capacity of the little liquid going backward quantity and when inclining the little fluid leak etc sufficiently it plays the effect which you say and is superior.吸水性樹脂及び接着剤を含有してなる吸収層が、不織布により該吸収層の上方及び下方から挟持された構造を有する吸水シート構成体であって、空隙率が91~99%である繊維基質により、該吸収層が1次吸収層と2次吸収層とに分割されてなる構造を有し、該吸水性樹脂の含有量が100~1000g/m2、該接着剤の含有割合が吸水性樹脂の含有量(質量基準)に対して0.05~2.0倍である吸水シート構成体。本発明にかかる吸水シート構成体は、薄型であっても、形態保持性が良好なために、液体吸収前や吸収後に型くずれを起こさず、しかも液体浸透性、少ない液体逆戻り量、傾斜時の少ない液漏れ等の吸収能力を十分に発揮することができるという優れた効果を奏する。
