摘要： 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.

摘要： An absorbent article has front and back surface sheets, and an absorbent body disposed within the front surface sheet and back surface sheet laminate. The absorbent article is further provided with a stretchable waist member disposed within the laminate in a manner enabling stretching in the width direction, and a pair of stretchable side members formed on the peripheral edge of the laminate in a manner enabling stretching in the width direction. One member and the other member of the pair of stretchable side members are formed, respectively, on one end and the other end of the laminate in the width direction. The stretchable waist member overlaps with each of the pair of stretchable side members in the lengthwise direction, is disposed further on the non-skin side than the absorbent body in the thickness direction, and overlaps with the absorbent body in the thickness direction but is not joined thereto.
