This disposable diaper (10) is configured in a manner so that the end (E2) at the front torso encircling region (20) side of an extendable/contractable range in a leg extension/contraction section (75) is more proximal to the end (E4) at the front torso encircling region (20) side of the disposable diaper (10) than the end (E3) at the front torso encircling region (20) side of an extendable/contractable range of a crotch extension/contraction section (200a). The end (E5) at the back torso encircling region (30) side of the extendable/contractable range in the leg extension/contraction section (75) is configured in a manner so as to be more proximal to the end (E7) at the back torso encircling region (30) side of the disposable diaper (10) than the end (E6) at the back torso encircling region (30) side of the extendable/contractable range of the crotch extension/contraction section (200a). The tensile modulus of the crotch extension/contraction section (200a) is greater than the tensile modulus of the leg extension/contraction section (75).
