The diaper includes an absorbent assembly 2 containing an absorbent member and a side panel 3. The side panel 3 includes two sheets 31, 32 and a plurality of elastic members 33 fixed between two sheets 31, 32 in their stretched state in the lateral direction of the diaper and has a fastening member 4 provided at its distal end. The side panel 3 has a plurality of bonded regions formed by applying an adhesive between the two sheets 31, 32, each bonded region being continuous in the diaper longitudinal direction. The bonded regions include a proximal bonded region 35 where an end or nearly an end of each elastic member 33 is fixed and a distal bonded region 36 where the other end or nearly the other end of each elastic member 33 is fixed. The intermediate region 37 between the proximal and the distal bonded region 35, 36 has one or more non-bonded regions 38 with no adhesive applied. The proximal and the distal bonded region 35, 36 are different width.本創作之拋棄式尿布包括含有吸收體之吸收性本體2與側片3。側片3包含2塊片材31、32與在沿尿布寬度方向伸長之狀態下固定於其等之間之複數根彈性構件33,且於前端側設置有固著材4。側片3係於2塊片材31、32間包含複數根沿尿布長度方向連續地配置有黏接劑之黏接區域,作為該黏接區域,包含固定彈性構件33之端部或其附近之本體側及前端側之黏接區域35、36,於夾於兩黏接區域35、36間之中間區域30,包含未配置黏接劑之一個或複數個非黏接區域38、38。本體側及前端側之黏接區域35、36之寬度不同。2‧‧‧吸收性本體3‧‧‧側片3a‧‧‧上下緣3b‧‧‧上下緣3c‧‧‧前端4‧‧‧固著材30‧‧‧中間區域31‧‧‧片材33‧‧‧彈性構件35‧‧‧本體側黏接區域36‧‧‧前端側黏接區域37‧‧‧中間黏接區域38‧‧‧非黏接區域41‧‧‧固著部W5‧‧‧寬度W6‧‧‧寬度W7‧‧‧寬度W8‧‧‧寬度W30‧‧‧寬度X‧‧‧方向Y‧‧‧方向
