PROBLEM TO BE SOLVED: To provide an absorbent article in which liquid leakage is suppressed. A liquid-impermeable sheet 40, an absorber 10, and a liquid-permeable sheet 30 are provided, and the liquid-impermeable sheet 40, the absorber 10, and the liquid-permeable sheet 30 are arranged in this order. Disclose the article. The absorber 10 contains the water-absorbent resin particles 10a, and has a light transmittance of 20% or more at a wavelength of 425 nm when the water-absorbent resin particles 10a are swollen 30 times with physiological saline. [Selection diagram] Figure 1【課題】液体漏れが抑制された吸収性物品を提供すること。【解決手段】液体不透過性シート４０、吸収体１０、及び液体透過性シート３０を備え、液体不透過性シート４０、吸収体１０及び液体透過性シート３０がこの順に配置されている、吸収性物品を開示する。吸収体１０は、吸水性樹脂粒子１０ａを含み、生理食塩水で３０倍に膨潤させたときの吸水性樹脂粒子１０ａの波長４２５ｎｍにおける光透過率が、２０％以上である。【選択図】図１
