Abstract
Described is an absorbent article that includes at least a liquid-permeable sheet, a liquid-impermeable sheet, and an absorption body sandwiched between the liquid-permeable sheet and the liquid-impermeable sheet. A pair of right and left compressed grooves are formed along the longitudinal direction. Each compressed groove is separated into a right or left compressed groove located in the longitudinal side edge part at least in the center region of the absorption body, a front-side compressed groove located in the longitudinal front part of the side edge part, and a rear-side compressed groove located in the longitudinal rear part of the side edge part and out of these compressed grooves. The compressed groove located on the widthwise innermost side is formed to allow its end part in the separation portion to run in parallel with the longitudinal centerline or face outwardly in the width direction.
