A side panel (3) is joined to an outer layer composite sheet (22) and a skin-side sheet (20) disposed on the inner-surface side of the side panel (3) via a connecting adhesive layer. The connecting adhesive layer (62) joins the side panel (3) and the outer layer composite sheet (22) on the outside of the inner side edge (3c) of the side panel (3), and joins the outer layer composite sheet (22) and a surface sheet (21) on the inside of the inner side edge (3c) of the side panel (3), in the width direction of the disposable diaper. An outer-layer adhesive layer (61) has an intermittent portion (7) where no adhesive is disposed at a position overlapping the inner side edge (3c) of the side panel (3) in the thickness direction (Z) of the disposable diaper.本發明之拋棄式尿布中，側片(3)經由連接用接著劑層接合於外層複合片材(22)、及配置於側片(3)之內表面側之肌膚側片材(20)。連接用接著劑層(62)係於拋棄式尿布之寬度方向上，在較側片(3)之內方側緣(3c)更靠外方側，將側片(3)與外層複合片材(22)接合，且在較側片(3)之內方側緣(3c)更靠內方側，將外層複合片材(22)與表面片材(21)接合。外層接著劑層(61)於拋棄式尿布之厚度方向(Z)上與側片(3)之內方側緣(3c)重疊之位置具有未配置接著劑之間斷部(7)。
