An absorbent member (20) includes an absorbent sheet (10) in which absorbent polymer (12) is fixed to a base sheet (11) and a cover sheet (21) covering at least a first surface of the absorbent sheet (10). The absorbent sheet (10) has an absorbent polymer fixing proportion of 40% or more. The absorbent member (20) has high fixing performance of the absorbent polymer (12) to the base sheet (11) and is less likely to suffer from detachment of the absorbent polymer (12) even after liquid absorption. The absorbent polymer (12) is preferably fixed to the base sheet (11) with a base sheet fixing adhesive (13) interposed therebetween. The adhesive (13) is preferably an acrylic, silicone-based or rubber-based adhesive, and is preferably a hot-melt adhesive.
