To provide an absorbent article capable of preventing a body fluid from remaining in a fiber aggregate layer of a top sheet, the top sheet of the absorbent article, and a manufacturing method of the top sheet. SOLUTION: The top sheet 2 of the absorbent article includes a resin film layer 31, the fiber aggregate layer 32, and a blood modifying agent layer 33, and comprises a plurality of protrusions 21 arranged in parallel and bottom sections 22 disposed between the adjacent protrusions 21. Each of the protrusions 21 includes, on a side face, a wall part 24 where the resin film layer 31 has a plurality of openings 34 arranged in the extending direction of the protrusion. The fibers of the fiber aggregate layer are covered with the blood modifying agent of the blood modifying agent layer 33. The blood modifying agent has IOB of 0 to 0.60, a melting point of 45[deg.]C or lower, and a water solubility of no more than 0.05 g in 100 g of water at 25[deg.]C.本發明為提供一種可抑制於表層薄片的纖維集合層之體液殘存的吸收性物品、其吸收性物品的表層薄片及其表層薄片之製造方法。本發明的吸收性物品之表層薄片(2)含有樹脂薄膜層(31)、纖維集合層(32)與血液改質劑層(33),具備並列配置之複數突條部(21)、與於鄰接之突條部(21)之間所配置之底部(22),突條部(21)為樹脂薄膜層(31)於突條部之延伸方向具有並列的複數開口部(34)的壁部(24)含於其側面,前述纖維集合層的纖維藉由血液改質劑層(33)之血液改質劑覆蓋,血液改質劑為具有0~0.60的IOB、45℃以下的熔點、對於25℃的水100g之0.05g以下的水溶解度。1‧‧‧吸收性物品2‧‧‧表層薄片3‧‧‧背面薄片4‧‧‧吸收體5‧‧‧翅膀部7‧‧‧密封部
