To provide an absorbent article allowing no generation of twisting, realizing a wide contact area of the absorber with skin, and enabling the absorbing layer center part to always obtain a stable deformed state. An absorbent article comprising at least a liquid-permeable sheet, a liquid-impermeable sheet, and an absorber sandwiched between the liquid-permeable sheet and the liquid-impermeable sheet, wherein: the absorber consists of absorbing layer center part and an absorbing part formed in the periphery of the absorbing layer center part to have a lower basis weight than the absorbing layer center part； on the skin-contact surface side of the absorbent article, compressed grooves are provided at least to exhibit symmetry with respect to the longitudinal centerline and surround the absorbing layer center part, the compressed grooves having a pair of right and left intermittent portions formed across the longitudinal centerline； and on the skin-non-contact surface side of the absorber, a space part being nearly convex toward the skin-contact surface side and formed between the absorber and the liquid-impermeable sheet, is present in the side part of at least a part of a compressed groove out of the compressed grooves provided along widthwise right and left side edges.
