The topsheet1comprises a first layer11disposed on the side of a wearer and a second layer12disposed 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.
