An absorbent article 200 has an improved ability to prevent the sacral part and coccygeal part being soiled by urine. The absorbent article 200 has a lower layer absorbent part 10 and, positioned above this, an upper layer absorbent part 20. Within the upper layer absorbent part 20, an upper layer front side portion 20F constituting the front side with respect to a coccyx facing portion TP is formed by a left side portion 30 and a right side portion 40. Their side edges facing the center in the width direction are configured to align with or come close to each other at a back rear end portion, extend forward from the back rear end portion with an increasing separation distance therebetween. The left side portion and the right side portion rise toward the skin of a wearer by contractile action of the tip-portion resilient and elastic member. Further, a clearance between an upper layer back rear side portion 20B and the lower layer absorbent part 10 is formed as a pocket 50 with an entrance at the separation section between the right side portion 40 and the left side portion 30.
