A water-absorbent sheet structure (10) including a structure in which an absorbent layer (13) containing a water-absorbent resin (12) and an adhesive (11) is sandwiched with nonwoven fabrics from an upper side and a lower side of the absorbent layer, the water-absorbent sheet structure (10) comprising (1) an upper nonwoven fabric (14) which is a water-permeable nonwoven fabric having a water permeation rate of 10 s or less and (2) a lower nonwoven fabric (15) which is a water-retaining nonwoven fabric having an amount of water absorbed of 250 g/m 2 or more. The water-absorbent sheet structure (10) of the present invention is thin and is capable of sufficiently exhibiting water-absorbent capacities such as fast liquid permeability, a small amount of liquid re-wet, and a small amount of liquid leakage. Therefore, the water-absorbent sheet structure (10) according to the present invention is used for an absorbent material, whereby hygienic materials which are thin and have excellent body fittability can be provided.一種吸水片材結構體及吸收性物品,該吸水片材結構體具有含有吸水性樹脂及接著劑而成之吸收層係藉由不織布自該吸收層之上方及下方夾持之構造者;且(1)上方之不織布係透水速度為10秒以下之透水性不織布;(2)下方之不織布係吸水量為250 g/m2以上之保水性不織布;該吸收性物品係使該吸水片材結構體夾持於液體透過性片材與液體不透過性片材之間者。本發明之吸水片材結構體為薄型,且能取得可充分地發揮較快之液體滲透性、較少之液體回流量及較少之漏液量等之吸收能力之優異效果,因此,藉由將本發明之吸水片材結構體用作吸收體,而可提供較薄且對身體之服貼性等優異之衛生材料。10‧‧‧吸水片材結構體11‧‧‧接著劑12‧‧‧吸水性樹脂13‧‧‧吸收層14‧‧‧透水性不織布15‧‧‧保水性不織布
