Abstract
There is provided an absorbent article including: a support sheet; a liquid-absorbing layer disposed on the support sheet; and a liquid-permeable surface sheet covering the liquid-receiving face of the liquid-absorbing layer. Between the liquid-absorbing layer and the surface sheet, there is provided a liquid-permeable layer of crimped fibers which remain in a crimped state in a natural state without any external force. The crimped fiber layer is formed by interconnecting the crimped fibers to leave voids therebetween.
