A water-absorbent sheet composite (10) having such a structure that an absorbent layer which contains both a water-absorbent resin (12) and an adhesive (11) is sandwiched by non-woven fabric sheets (16, 17), wherein: the absorbent layer is thicknesswise divided by a textile substrate (15) into a primary absorbent layer (13) and a secondary absorbent layer (14) the content of the water-absorbent resin (12) is 100 to 600g/m2 the content of the adhesive (11) is 0.05 to 2.0 times (by mass) that of the water-absorbent resin (12) and the ratio of the mass of the water-absorbent resin (12) in the primary absorbent layer (13) to the total mass of the water-absorbent resin (12) in the primary and secondary absorbent layers (13, 14) is 15 to less than 50%. An absorbent article wherein the water-absorbent sheet composite (10) is sandwiched between a liquid-permeable sheet and a liquid -impermeable sheet.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,且具有藉由纖維基質將上述吸收層於上下分割為1次吸收層與2次吸收層而成之構造,上述吸水性樹脂之含量為100~600 g/m2,上述接著劑之含量相對於吸水性樹脂之含量(質量基準)為0.05~2.0倍,1次吸收層之吸水性樹脂之質量相對於1次吸收層與2次吸收層之吸水性樹脂之合計質量之比例為15%以上且未達50%,該吸收性物品係使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。10‧‧‧吸水片材結構體11‧‧‧接著劑12‧‧‧吸水性樹脂13‧‧‧1次吸收層14‧‧‧2次吸收層15‧‧‧纖維基質16‧‧‧不織布17‧‧‧不織布
