PROBLEM TO BE SOLVED: To provide nonwoven fabric having increased liquid permeability and air permeability. SOLUTION: This nonwoven fabric is constituted with conjugated continuous filaments. The continuous filament are produced by conjugating a low-melting thermoplastic polymer component A and a high-melting thermoplastic polymer component B. The component A and the component B are exposed to the surface of the fiber. In the nonwoven fabric, the fusing areas and the fiber-split areas are arranged to that they may become mutually adjacent. In the fiber-split area, the fibers A made of only split polymer A, the fibers B made of only split polymer B and not-split conjugated continuous filaments distribute as they form the regions in which they are entangled substantially in the three dimension and the regions in which open pores are formed. |
