Abstract
A rear elastic area formed by a rear waist region with rear waist elastic members stretchable laterally across the rear waist region. A front elastic area formed by a front waist region with front waist elastic members stretchable laterally across the front waist region. The rear waist region and the front waist region are capable of stretching or contracting in unison. A greater number of rear waist elastic members than front waist elastic members are provided. The rear elastic area is broader than the front elastic area with respect to the longitudinal direction of the diaper body. The body-hugging capability of the diaper body at the rear waist side of the wearer is increased so that the diaper body is prevented from slipping down. This configuration reduces constructive feeling by ensuring that the diaper body is not excessively tight at the front waist side of the wearer.
