Abstract:
An absorbent article has a lower absorbing core and an upper absorbing core. Each absorbing core includes a liquid-holding material and a liquid-permeable core-wrapping sheet. The liquid-holding material is covered by the liquid-permeable core-wrapping sheet, but it also has an exposed portion not covered by the liquid-permeable core-wrapping sheet. The exposed portions of the lower absorbing core and the upper absorbing core face each other and the liquid-holding materials are connected with each other at the exposed portion. Because the liquid-holding material of the upper absorbing core is in direct contact with the liquid-holding material of the lower absorbing core, the area provides a path through which liquid flows smoothly from the upper absorbing core to the lower absorbing core. Also, because the upper and lower liquid-holding materials are covered by the core-wrapping sheets, deformation of the liquid-holding materials is prevented.
