摘要： An absorbent article which comprises an absorbent element which at least partially comprises an absorbent sheet A prepared by applying a pressure-sensitive adhesive 3 having a suitable adhesive power to an absorbent material 1 having a suitable liquid-absorbent (or retentive) power in the form of dot, line or curve (spiral curve or the like) with the pressure-sensitive adhesive in a suitable density; spreading an absorbent polymer 2 thereon; putting another sheet of the absorbent material 1 thereon, and compressing the assemblage into a composite structure. In the course of the absorption of a liquid, the liquid is first stocked in the absorbent material having a high initial absorption velocity, and is gradually transferred to the absorbent polymer by capillary power as the driving force and absorbed therein, while the absorbent polymer is prevented from falling off from the absorbent material by the pressure-sensitive adhesive, whereby the properties of the absorbent polymer can be exhibited to the fullest.
