<p>An absorptive sheet (2) comprises highly absorptive polymer particles (6) deposited onto constituent fibers of a fibrous base material (5) and is flexible or elastic. The highly absorptive polymer particles (6) are prepared by depositing a liquid containing a polymerizable monomer and/or its oligomer onto the fiber and polymerizing the polymerizable monomerand/or its oligomer. The fibrous base material (5) preferably comprises a flexible or elastic nonwoven fabric or continuous filament. Preferably, the basis weight of the fibrous base material (5) is 20 to 100 g/m<SUP>2</SUP>, and the amount of the highly absorptive polymer deposited onto the fibrous base material (5) is 50 to 500 g/m<SUP>2</SUP>. The stress at 20% elongation of the absorptive sheet (2) is preferably 0.2 to 4.0 N based on 1-cm width.</p>
