PROBLEM TO BE SOLVED: To sufficiently exert an antibacterial effect by an antibacterial agent, and the absorption performance is not deteriorated. SOLUTION: An antibacterial non-woven fabric composed of a fiber 10 having a fiber treatment agent 11 adhered to the surface thereof and an antibacterial agent is arranged on the skin side of an absorber 4. The antibacterial agent is composed of the antibacterial agent 12 in the fiber kneaded into the fiber 10 and the antibacterial agent 13 in the fiber treatment agent mixed with the fiber treatment agent 11. It is preferable to use a hydrophilic agent as the fiber treatment agent. The amount of the antibacterial agent remaining on the antibacterial nonwoven fabric after the body fluid is discharged is larger than the amount of the antibacterial agent eluted from the antibacterial nonwoven fabric with the discharge of the body fluid. The antibacterial non-woven fabric constitutes at least a part of the surface sheet 3, the second sheet 8 or the encapsulated sheet 9. The antibacterial agent 12 in the fiber is made of an inorganic antibacterial agent which is poorly soluble in water, and the antibacterial agent 13 in the fiber treatment agent is made of an organic antibacterial agent which is soluble in water. [Selection diagram] Fig. 6【課題】抗菌剤による抗菌効果が充分に発揮でき、吸収性能が低下することがない。【解決手段】吸収体４の肌側に、表面に繊維処理剤１１が付着した繊維１０と、抗菌剤とからなる抗菌性不織布が配設されている。前記抗菌剤が、前記繊維１０中に練り込まれた繊維中抗菌剤１２と、前記繊維処理剤１１に混合された繊維処理剤中抗菌剤１３とから構成される。前記繊維処理剤として親水化剤を用いるのが好ましい。体液の排出に伴って前記抗菌性不織布から溶出する前記抗菌剤の量より、体液排出後に前記抗菌性不織布に残存する前記抗菌剤の量の方が多くなっている。前記抗菌性不織布は、表面シート３、セカンドシート８又は被包シート９の少なくとも一部を構成している。前記繊維中抗菌剤１２は水に対して難溶性の無機系抗菌剤からなり、前記繊維処理剤中抗菌剤１３は水に対して可溶性の有機系抗菌剤からなる。【選択図】図６
