The topsheet contains hydrophobic fibers and hydrophilic fibers shorter than the hydrophobic fibers. The hydrophobic fibers are thermally bonded to each other. At least a part of the hydrophilic fibers form aggregates that disperse in the sheet. At least a part of the hydrophilic fibers that form the aggregates are bonded to the surfaces of the hydrophobic fibers.
