A disposable absorbent article improved so that occurrence of defecation may be easily perceived from the outside. A diaper 1 as one example of a disposable absorbent article includes a crotch inner sheet 28 lying on a skin-facing surface, a crotch outer sheet 29 lying on a non-skin-facing surface and a liquid-absorbent structure 80 interposed between these inner and outer sheets 28, 29. In this diaper 1, a total luminous transmittance from the outer sheet 29 through the liquid-absorbent structure 80 to the inner sheet 28 is in a range of 15% to 65%. The liquid-absorbent structure 80 has a longitudinal direction Y, a transverse direction X and a thickness direction W and includes a first sheet 81 and a second sheet 82 overlapping each other and absorbent polymer particles 84 interposed between these first and second sheets 81, 82 wherein the liquid-absorbent structure 80 is divided into absorbing regions 85 in which the absorbent polymer particles 84 are present and sealing regions 86 in which none of the absorbent polymer particles 84 is present arranged alternately in the in the longitudinal direction Y. In the sealing regions 86, the first sheet 81 and the second sheet 82 are bonded to each other.
