2A three dimensional nonwoven fabric (1) with a pore structure comprises raised regions (B) recessed regions (A) and the pore structure (D). The raised regions (B) and the recessed regions (A) are defined on the basis of a nonwoven application surface. Fiber densities from the raised regions (B) to the recessed regions (A) are gradient that is the fiber density of the edges (C) transiting from the raised regions (B) to the recessed regions (A) is higher than that of the tops of the raised regions (B) and the fiber density of the edges (C) is 1.5 to 30 times of the fiber density of the tops of the raised regions (B) the fiber density of the recessed regions (A) is 1.5 to 20 times of the fiber density of the tops of the raised regions (B) a height difference between the raised regions (B) and the recessed regions (A) is greater than 0.2 mm the average area of each single pore of the pore structure (D) is smaller than 20 mm and the porosity is lower than 50% and the area of the raised regions (B) accounts for 20 to 80% of the total area of the three dimensional nonwoven fabric (1). Pressure resistance performance of the high density fiber regions keeps the three dimensional nonwoven fabric (1) significantly uneven and quickens liquid permeation and reduces residues and the three dimensional nonwoven fabric (1) has a high permeating speed and is dry and comfortable.
