PROBLEM TO BE SOLVED: To provide an absorbent article having an adhesive which can be stably adhered to underwear when an absorbent article is attached, and which is unlikely to remain in underwear (peeling residue hardly occurs) when the absorbent article is peeled off. SOLUTION: An absorbent article (example: sanitary napkin 10) has a non-woven fabric (example: back sheet 13) arranged on the non-skin side, and an adhesive for fixing clothes applied to the non-skin side surface of the non-woven fabric. Agent 40, and. The pressure-sensitive adhesive includes the impregnated portion 45 impregnated in the nonwoven fabric. The ratio of the thickness of the impregnated portion to the thickness of the adhesive is 30 to 80%. The storage elastic modulus of the pressure-sensitive adhesive is 1.0×10 4 to 2.0×10 5 Pa at 50° C.
