A topsheet for absorbent articles having absorbing performance for smoothly transferring liquid body waste, e.g., menstrual blood or urine, to an underlying absorbent member and surface characteristics such that the surface thereof in contact with wearer's skin is soft enough not to cause skin irritation. The topsheet 1 comprises a first layer 11 disposed on the side of a wearer and a second layer 12 disposed on the side of an absorbent member, the first layer and the second layer being partly joined together, and having protrusions and depressions on the side of a wearer, wherein the first and second layers each comprise a fiber aggregate, the first layer has fusion-bonded fiber intersections, the first layer has an apparent thickness (t1) of 0.1 to 5 mm, the second layer has an apparent thickness (t2) of 0.2 to 3 mm, the apparent thickness ratio of the first layer to the second layer (t1/t2) is 0.5 to 8, the first layer has a fiber density (d1) of 0.001 to 0.05 g/cm3, the second layer has a fiber density (d2) of 0.03 to 0.2 g/cm3, and the fiber density (d2) of the second layer is higher than that (d1) of the first layer.
