PROBLEM TO BE SOLVED: To provide a pants-type disposable diaper in which a disposal tape is not easily broken even though the disposal tape is stretchable and has good operability. SOLUTION: A disposal tape 10 is provided on the outer surface of a diaper 1. The disposal tape 10 is in a tri-folded state in which the fixing portion 12, the extending portion 15, and the fastening portion 18 are arranged in this order along the longitudinal direction X1 of the disposal tape 10 and are laminated in this order. The extending portion 15 can be extended in the longitudinal direction X1 of the disposal tape 10 in the unfolded state in which the tri-folded state is released. The waste tape 10 has a first connecting region 31 in which the extending portion 15 and the fastening portion overlap, and a second connecting region 32 in which the extending portion 15 and the fixing portion 12 overlap, and one of these connecting regions. Alternatively, both have a weak joint portion 36 and a strong joint portion 33 having a higher peel strength than the weak joint portion 36, and the weak joint portion 36 is located closer to the central portion in the longitudinal direction X1 than the strong joint portion 33. ..
