< Topic >When binds section 2C1 is provided in absorber 2C, absorption efficiency of desire is made to show. SolutionsWith the disposable diaper 1 which relates to this execution form, position of maximum breadth Wnax of absorber 2C compared to outside product crosswise W, elastic member 3 around the leg of expansion and contraction possibility 1 pair is provided at least in product longitudinal direction L, at the same time elastic member 3 around the leg compared to inside product crosswise W position of maximum breadth Wmax1/Wmax2 of absorber 2C compared to outside product crosswise W, the inside elastic member 4 of expansion and contraction possibility 1 pair is provided at least in product longitudinal direction L, binds in ventral side F, section 2C1 elastic member 3 around the legThe range R1 of effective length compared to we have arrived to outside product longitudinal direction L, bind the edge E1 of ventral side F of the effective length of the inside elastic member 4, it exists inside range R2 where section 2C1 is provided in product longitudinal direction L. < Selective figure >Drawing 1【課題】吸収体2Cに括れ部2C1が設けられている場合であっても、所望の吸収性能を発揮させる。【解決手段】本実施形態に係る使い捨ておむつ1では、吸収体2Cの最大幅Wnaxの位置よりも製品幅方向Wの外側に、製品長手方向Lに伸縮可能な少なくとも1対の脚回り弾性部材3が設けられており、脚回り弾性部材3よりも製品幅方向Wの内側で且つ吸収体2Cの最大幅Wmax1/Wmax2の位置よりも製品幅方向Wの外側に、製品長手方向Lに伸縮可能な少なくとも1対の内側弾性部材4が設けられており、腹側Fにおいて、括れ部2C1は、脚回り弾性部材3の有効長の範囲R1よりも製品長手方向Lの外側にまで到達しており、製品長手方向Lにおいて、内側弾性部材4の有効長の腹側Fの端縁E1は、括れ部2C1が設けられている範囲R2内に存在する。【選択図】図1
