Abstract

In a disposable diaper, ends at a front waistline region side of the disposable diaper within a stretchable range in leg stretch units are configured so as to be closer to an end at the front waistline region side as compared to an end at the front waistline region side within a stretchable range in the crotch stretch unit. Ends at a rear waistline region side within the stretchable range in the leg stretch units are configured so as to be closer to an end at the rear waistline region side as compared to an end at the rear waistline region side within the stretchable range in the crotch stretch unit. A tensile modulus of the crotch stretch unit is configured so as to be greater than a tensile modulus of the leg stretch units.
