Abstract
An absorbent article is provided that improves adhesion to the skin and reduces leaks of bodily fluids by ensuring stable deformation thereof. The absorbent article has a liquid-permeable top sheet disposed on body-facing side of the absorbent article; a liquid-impermeable back sheet disposed on a clothing-facing side of the absorbent article; and a liquid-retainable absorbent body disposed between the top sheet and the back sheet. The absorbent body has a compressed channel formed into a concave shape in the body-facing side; and a space formed into a convex shape in the clothing-facing side toward the body-facing. The space is formed on both sides or on one side of a channel backside located on an opposing side of the compressed channel portion in the clothing-facing side.
