In view of the challenges specific to an absorbent article with leakage prevention grooves, the disclosed absorbent article seeks to mitigate the reduction in flexibility of the entire absorbent body engendered by the leakage prevention grooves and, while preventing the spread of liquid due to side leakage, to effectively use the absorbent core inside and outside of the leakage prevention grooves depending on the amount of excretion. The absorbent article is a hygienic napkin which has a liquid permeable front surface sheet disposed on the side of the surface contacting the skin, a liquid permeable rear surface sheet disposed on the side of the surface not contacting the skin, and an absorbent core disposed between the aforementioned two sheets. The aforementioned absorbent core has a length direction and a width direction orthogonal thereto. Said absorbent core has multiple separation gaps extending along the width direction thereof, and the aforementioned separation gaps of the aforementioned absorbent core are also formed along the length direction thereof. The aforementioned absorbent core is formed from a collection of horizontally and vertically independent small absorption units. Leakage prevention grooves are formed in said absorbent core extending in the length direction, traversing one or more of the aforementioned separation gaps, and compressed, along with the aforementioned front surface sheet, from the side of said front surface sheet.本發明係為解決具有防漏槽之吸收性物品所特有之問題,提供一種可減緩因防漏槽所引起之吸收體整體之柔軟度下降,防止會導致側漏之液體擴散,並且可根據排泄量來有效使用防漏槽之內側及外側之吸收性芯體之吸收性物品。生理用衛生棉,其包含配置於貼膚面側之透液性之正面片材、配置於非貼膚面側之不透液性之背面片材、以及介於上述兩片材之間的吸收性芯體,且上述吸收性芯體具有長度方向以及與該長度方向正交之寬度方向,該吸收性芯體具有沿著其寬度方向延伸之複數個間隔部,並且沿著該吸收性芯體之長度方向亦形成有上述吸收性芯體之上述間隔部,上述吸收性芯體係以縱橫獨立之小吸收部之集合體而形成,且於該吸收性芯體中,形成有橫穿一個以上之上述間隔部而沿著長度方向延伸之與上述正面片材一併自該正面片材側受到壓擠而成之防漏槽。1...正面片材2...包圍片材3...吸收部5...防漏槽7...背面片材8...側面片材10...吸收性芯體81...自由端100...生理用衛生棉A、B...吸收部行d、e...間隙g...周緣封條h1...長度方向長度h2...寬度方向長度P...長度方向中央部ta、tb...輔助線
