Disclosed is an absorbent article containing an absorbent body which is thin before absorption, and even after absorption does not inhibit super absorbent polymer (SAP) swelling and wherein deformation such as twisting is unlikely to occur. The disclosed absorbent article comprises a liquid-permeable front surface sheet, a liquid impermeable rear surface sheet, and an absorbent body which is located between the two sheets. The absorbent body is formed from a super absorbent polymer containing layer and a non-woven fabric layer, with the non-woven fabric layer having regions wherein the between-fibre void ratio is relatively large and regions wherein the between-fibre void ratio is relatively small. The tip sections of the fibres forming the non-woven fabric layer are greater in number in the regions wherein the between-fibre void ratio is relatively large than the regions wherein the between-fibre void ratio is relatively small, and the non-woven fabric layer has expansibility.
