A nonwoven fabric made of filaments, which comprises filaments formed from a fiber-forming thermoplastic polymer and satisfies all of the following conditions (A) to (D). (A) The fiber bundles are present in a range of 5-70 per centimeter in any cross-section parallel to the direction of thickness of the nonwoven fabric. (B) The total area occupied by the fiber bundles is in a range of 5-70% of the cross-sectional area of any cross-section perpendicular to the direction of thickness of the nonwoven fabric. (C) The apparent density is 0.10-0.50 g/cm<3>. (D) The cut ends of the fibers on the nonwoven fabric surface are present in a range of 5-100 per mm<2> of surface area.
