发明名称 Absorbent article
摘要 An absorbent article ensuring that even when excreted urine diffuses by running down the wearer's skin, the urine is prevented from leaking out of the absorbent article. The absorbent article comprises an absorbent sheet that has at least one absorbent polymer-existing region in which the absorbent polymer is sandwiched by at least one liquid-pervious sheet and at least one absorbent polymer-nonexisting region which is free of absorbent polymer. The at least a part of the absorbent sheet is disposed in a rear waist region, and a planar shape of the absorbent polymer-existing region disposed on the rear waist region side of the longitudinal center of the crotch region of the absorbent sheet is a nearly V-shaped with an apex facing in the direction from the front waist region to the rear waist region in the longitudinal direction of the absorbent article.
