PROBLEM TO BE SOLVED: To provide a disposable diaper capable of absorbing excrement from a whole peripheral face of an absorption element and preventing the excrement from being leaked to outside even when the excrement is a large amount.SOLUTION: On both side parts of an interior body in a width direction, three-dimensional gathers 60 extended in a front/rear direction and including an elastic expandable/contractable member are arranged. The interior body includes: a liquid impermeable sheet 11 arranged on an opposite side to a body; a center absorption element 50 arranged in a center part of the liquid impermeable sheet in a width direction, covered with a surface sheet, and extended in the front/rear direction; and a right absorption element 51 and left absorption element 52 arranged on both side parts of the center absorption element in the width direction, covered with a surface sheet, and extended in the front/rear direction. An opposite side with respect to the center absorption element of the right absorption element and left absorption element on an opposite side to the body is fixed on a body face of the liquid impermeable sheet. A center part of the center absorption element on an opposite side to the body is fixed on the body face of the liquid impermeable sheet. Both side parts of the center part are not fixed on the body face of the liquid impermeable sheet.SELECTED DRAWING: Figure 7【課題】吸収要素のほぼ全周面から排泄物を吸収可能として多量の排泄物があった場合においても排泄物が外部への漏れ出しを防止する使い捨ておむつを提供する。【解決手段】内装体の幅方向の両側部に、前後方向に延在する弾性伸縮部材を備えた立体ギャザー60を設け、内装体を、反身体側に設けられた液不透過性シート11と、液不透過性シートの幅方向の中央部に設けられ、表面シートによって覆われた前後方向に延在する中央吸収要素50と、中央吸収要素の幅方向の両側部に、表面シートによって覆われ前後方向に延在する右側吸収要素51、左側吸収要素52を設け、右側吸収要素、左側吸収要素の反身体面における中央吸収要素とは反対側部を、液不透過性シートの身体面に固定し、中央吸収要素の反身体面の幅方向の中央部を、液不透過性シートの身体面に固定し、中央部の両側部を、液不透過性シートの身体面に対して非固定とすることにより解決される。【選択図】図7
