The present invention relates to an absorbent article for improving the flexibility of the absorber and thereby improves the breathability. The absorbent article comprising: a liquid permeable top surface sheet (14), a liquid impermeable back surface sheet (12), and an absorber (13) disposed between the top surface sheet (14) and the back surface sheet (12). The grooves (21) extend on a top surface sheet (14) side of the absorbent article, and in each of the grooves (21), a plurality of recess portions formed by integrally joining the top surface sheet (14) and the absorber (13) are arranged. Each of the recess portions has a sidewall (21d) and a bottom (21c). A compression ratio of the absorber (13) is 4 to 7 times at each of the recess portions.
