Abstract
An absorbent article worn in the groin area, in which, when a compressive force is received from a lateral direction, a main absorbent region can oppose an excretion area of a wearer's body without twists or wrinkles occurring, and when the compressive force is relaxed, the article easily recovers to its original shape. An absorbent body provided in the absorbent article has a main absorbent region, reinforcing regions, and buffer regions. The bending stiffness of the reinforcing regions and the main absorbent region is larger than that of the buffer regions. When compressive force is received from a wearer's thigh areas in the lateral direction, the reinforcing regions that are positioned to the left and right deform in a curved shape, and the buffer regions that are to the left and right are compressed. The main absorbent region does not easily deform, and maintains a tight fit.
