The utility model provides non-woven fabric for a diaper and the diaper using the non-woven fabric. Even though the diaper becomes thin, the diaper still can store a large amount of urine. The non-woven fabric for the diaper is provided with a first fiber layer (21) with a concave-convex surface (19) and a second fiber layer (22), wherein the concave-convex surface (19) is formed by a large number of concave portions (33) and convex positions (34) on the surface of the non-woven fabric, and the second fiber layer (22) is overlapped with the reverse side of the first fiber layer (21). The convex positions (34) protrude towards the opposite side of the second fiber layer (22) in a manner that the each convex position is of a roughly hexagon shape observed from the surfaces, and each concave portion (33) is of a groove shape corresponding to the edges of each roughly hexagon shape. Spot-shaped portions (50) are arranged at the positions corresponding to each corner of the roughly hexagon shape and are connected to the second fiber layer (22) in a hot pressing mode. The concave-convex surface (19) is of a honeycomb shape formed by the roughly hexagon shapes in a continuous arrangement mode.
