Provided is an absorbent article that has a thickness direction, a width direction, and a length direction and is used by being attached to underwear to absorb excreted liquid. The main body section of the absorbent article comprises an absorbent core that contains a liquid-absorbent material. The absorbent core has a protruding section, on the surface that faces the skin side in the thickness direction, that protrudes toward the skin side. The protruding section is formed in a ring shape that surrounds the central section in the length direction of the absorbent core and has, as the end sections in the width direction of the protruding section, a pair of linear portions that are aligned in the width direction and are parallel to the length direction. A leakage barrier section is provided along the length direction on the surface of the main body section facing the skin side in the thickness direction, and initial rise positions where the leakage barrier section begins to rise from such surface are set at positions corresponding to the linear portions.
