Zusammenfassung:	Provided are: a water absorbent laminate which comprises a first fiber layer that is configured of a first fiber assembly containing first hydrophilic fibers and a second fiber layer that is configured of a second fiber assembly containing 80% by mass or more of wet heat adhesive fibers, and wherein a surface of the first fiber layer, said surface being on the reverse side of the second fiber layer-side surface, has an water absorption rate of 10 seconds or less as determined in accordance with a dripping method defined in JIS L 1907; and a method for producing the water absorbent laminate. This water absorbent laminate can additionally comprise, between the first fiber layer and the second fiber layer, a third fiber layer that is configured of a third fiber assembly containing second hydrophilic fibers.
