Abstract:
1. An absorbent article comprising: a backsheet; an absorbent storage layer formed with compressed grooves, which are at opposite sides of a longitudinally extending centerline of the absorbent article and extend at least in the longitudinal direction; a liquid guide layer; and a top layer formed of at least one liquid-permeable layer, wherein the backsheet, the absorbent storage layer, the liquid guide layer, and the top layer are laminated one upon each other in the order named, wherein the absorbent storage layer, the liquid guide layer and the top layer satisfy the following relationships: the liquid guide layer is greater that the absorbent storage layer which is greater than the top layer with respect to a water absorbency due to capillary phenomenon; the liquid guide layer is greater than the absorbent storage layer which is greater than the top layer with respect to a retention ratio of a liquid dropped onto the top layer in an amount less than a maximum water absorption amount of the liquid guide layer; and the absorbent storage layer is greater than the liquid guide layer which is greater than the top layer with respect to a retention ratio of a liquid dropped onto the top layer in an amount more than the maximum water absorption amount of the liquid guide layer; wherein the water absorbency due to capillary phenomenon of the compressed grooves is higher than that of the liquid guide layer.
