To provide a disposable diaper excellent in the air permeability.SOLUTION: A disposable diaper is provided with an absorbent body 7 on a crotch part of a pants-shaped exterior member 2. The absorbent body 7 is bonded to a skin face side of the exterior member 2 in a first bonding region 14. An inner sheet 5 and an outer sheet 6 of the exterior member 2 are bonded to each other in a second bonding region 16. The second bonding region 16 includes a second intermediate bonding region 16M provided on the crotch part, a second front side bonding region 16F provided on the front side and a second rear side bonding region 16B provided on the rear side with respect to the second intermediate bonding region. The second front side bonding region 16F and/or second rear side bonding region 16B are intermittently provided from one side edge to the other side edge in the width direction x of the absorbent body 7. A second front side non-bonding region 17F and/or second rear side non-bonding region 17B are formed in a portion overlapped with the absorbent body 7, and provided so as to be overlapped with the one side edge and the other side edge in the width direction x of the first bonding region 14.SELECTED DRAWING: Figure 5【課題】通気性に優れた使い捨ておむつを提供する。【解決手段】パンツ形状の外装部材２の股部に吸収性本体７が設けられた使い捨ておむつであって、吸収性本体７は外装部材２の肌面側に第１接着領域１４で接着され、外装部材２の内側シート５と外側シート６は第２接着領域１６で互いに接着され、第２接着領域１６は、股部に設けられた第２中間接着領域１６Ｍとそれよりも前側に設けられた第２前側接着領域１６Ｆと後側に設けられた第２後側接着領域１６Ｂとを有し、第２前側接着領域１６Ｆおよび／または第２後側接着領域１６Ｂは、吸収性本体７の幅方向ｘの一方側縁から他方側縁にかけて断続的に設けられ、吸収性本体７と重なる部分に第２前側非接着領域１７Ｆおよび／または第２後側非接着領域１７Ｂが形成されるとともに、第１接着領域１４の幅方向ｘの一方側縁と他方側縁と重なって設けられている。【選択図】図５
