To provide a nonwoven fabric excellent in cushioning property, and capable of obtaining soft touch, and an absorbent article including the same.SOLUTION: A nonwoven fabric 10 of the present invention comprises a first layer 11 containing a thermally fusible fiber, and a second layer 12 containing a thermally shrinkable fiber, where both layers are adjacently arranged so that a second face 11r of the first layer 11 faces a first face 12f of the second layer 12. A first face 11f of the first layer 11 is convexo-concave-shaped, and the second face 11r is convexo-concave-shaped so as to correspond to the convexo-concave shape of the first face 11f. A second face 12r of the second layer 12 is flat. A plurality of convex parts 15 and concave parts 16 are formed on a first face F side of the nonwoven fabric 10 by bonding the first layer 11 and the second layer 12 at a position of a concave part 11b of the first face 11f of the first layer 11. When observing along a thickness direction Z of the nonwoven fabric 10, the convex parts 15 has a lower existing density of fibers in an order of a top part 15a, a middle part 15b, and the second layer 12.SELECTED DRAWING: Figure 2 【課題】クッション性に優れ、柔らかな感触が得られる不織布及びこれを含む吸収性物品を提供する。【解決手段】本発明の不織布１０は、熱融着性繊維を含む第１層１１と、熱収縮性繊維を含む第２層１２とを備え、第１層１１の第２面１１ｒと第２層１２の第１面１２ｆとが対向するように両層が隣接して配置されている。第１層１１の第１面１１ｆが凹凸形状であり且つ第２面１１ｒが第１面１１ｆの凹凸形状に対応する凹凸形状である。第２層１２の第２面１２ｒが平坦である。第１層１１と第２層１２とが、第１層１１の第１面１１ｆにおける凹部１１ｂの位置において接合されて、不織布１０の第１面Ｆ側に複数の凸部１５及び凹部１６が形成されている。不織布１０の厚み方向Ｚに沿って見たとき、凸部１５は、頂部１５ａ、中間部１５ｂ、及び第２層１２の順で繊維の存在密度が低い。【選択図】図２
