PROBLEM TO BE SOLVED: To provide an absorbent article capable of suitably diffusing liquid in a direction orthogonal to the extending direction of a groove part even in an absorber on which the groove part is formed.SOLUTION: The invention is based on the finding that, by disposing a highly absorptive polymer 22a of a low absorption speed near the groove part 14 of the absorber 3 and disposing a highly absorptive polymer 22b of a high absorption speed at a position remote from the groove part of the absorber, the liquid is gradually infiltrated from an area near the groove part of the absorber to the area remote from the groove part and diffusibility of the liquid by the absorber is improved.COPYRIGHT: (C)2012,JPO&INPIT【課題】溝部が形成された吸収体であっても,溝部が延設された方向と直交する方向に,液体を好適に拡散させることができる吸収性物品を提供する。【解決手段】吸収体3の溝部14の近傍に吸収速度の遅い高吸収性ポリマー22aを配設し,吸収体の溝部から遠隔の位置に吸収速度の早い高吸収性ポリマー22bを配設することにより,液体を吸収体の溝部近傍の領域から溝部遠隔の領域に向かって徐々に浸透させ,吸収体による液体の拡散性を向上させることができるという知見に基づく。【選択図】図2
