Water-absorbent laminar structure (1) comprising a structure in which an absorbent layer (2), which contains a water-absorbent resin, is interposed with a hydrophilic nonwoven fabric (4) from an upper face and a face bottom of the absorbent layer, characterized in that at least one face between an upper face and a lower face of the water-absorbent sheet structure is embossed (3), with an area proportion from 3% to 25% , on the basis of the embossed face area of the water-absorbent sheet structure, and because the water-absorbent sheet structure has the following properties: when a saline solution is allowed to be absorbed in an amount of 4 l per 1 m2 of the water-absorbent sheet structure (4 l / m2), the water-absorbent sheet structure satisfies the following two relationships (A) and (B): (A) an expansion thickness ratio, that is, a T2 / T1, 2 or higher, and (B) an embossing depth of expansion, that is, a (T2-t2) / T2, of 0.7 or greater, where T1 is a thickness (mm) of the water-absorbent sheet structure before the solution is absorbed saline； T2 is a thickness (mm) of the water absorbent sheet structure after absorption of the saline solution； and t2 is an embossing thickness (mm) of the water-absorbent laminar structure after absorption of the saline solution, and in which T1, T2 and t2 are thicknesses measured using the instrument with model number: LB series, manufactured by KEYENCE Corporation.Estructura laminar (1) absorbente de agua que comprende una estructura en la que una capa absorbente (2), que contiene una resina absorbente de agua, está interpuesta con un tejido no tejido hidrófilo (4) a partir de una cara superior y una cara inferior de la capa absorbente, caracterizada por que por lo menos una cara de entre una cara superior y una cara inferior de la estructura laminar absorbente de agua está sometida a un gofrado (3), con una proporción de área desde 3% a 25%, sobre la base del área de la cara sometida a gofrado de la estructura laminar absorbente
