An absorbent article for body fluids capable of absorbing and retaining booty fluids was recently patented. The absorbent article comprises an absorbent member that contracts on contacting body fluids. The absorbent member comprises a contraction material with a predetermined length and contracting on contacting body fluids an absorbent material for body fluids practically united with the contraction material. The absorbent material for body fluids comprises a highly absorbent polymer, a retaining carrier and the contraction material. The highly absorbent polymer of the absorbent member is arranged intermittently on the retaining carrier in the direction of contraction. The predetermined length of the absorbent member in the direction of contraction where the highly absorbent polymer is not arranged in the retaining carrier is adjusted to be from 30 to 400% of the length of the absorbent member in the direction of contraction where the highly absorbent polymer is arranged.
