To provide an absorbent article equipped with an indicator which has increased visibility and responsiveness and can detect a change in urine specific gravity.SOLUTION: An absorbent article includes a top sheet layer, an absorber layer, an indicator layer, and a leak prevention layer in this order. The absorber layer includes a core wrap layer for covering the absorbent core layer and at least a side of the leak prevention layer of the absorbent core layer. The indicator layer is adjusted to an appearance color of an alkali side in an initial state before making contact with urine, changes into a color corresponding to urine specific gravity in making contact with the urine, and is arranged between the core wrap layer and the leak prevention layer by directly bonding to the core wrap layer and the leak prevention layer at least partially.SELECTED DRAWING: Figure 2 【課題】本発明は、視認性及び応答性を向上させた、尿比重の変化を検知可能なインジケータを備えた吸収性物品を提供する。【解決手段】本発明の吸収性物品は、トップシート層、吸収体層、インジケータ層、及び防漏層をこの順に有しており、前記吸収体層は、吸収コア層及び前記吸収コア層の少なくとも前記防漏層側を被覆しているコアラップ層を有しており、前記インジケータ層は、尿と接触する前の初期状態においてアルカリ性側の外観色に調整され、尿に接触すると尿比重に応じた色に変色可能であり、かつ少なくとも部分的に、前記コアラップ層と前記防漏層とに直接接合されて、それらの間に配置されている、吸収性物品である。【選択図】図２
