PROBLEM TO BE SOLVED: To provide a nonwoven fabric having excellent liquid absorbability, rich flexibility and rich air permeability, and useful for various kinds of uses. SOLUTION: This opened nonwoven fabric is obtained by applying a high pressure columnar water flow treatment to a fiber web on a support for forming openings. The fiber web comprises 70-30 wt.% of hydrophilic fibers and 30-70 wt.% of split type conjugate fibers each comprising two different resins and having a fiber cross section in which at least one of the two components is divided into two or more divisions. The obtained nonwoven fabric has many opened holes penetrated from the front surface of the non-woven fabric to the back surface, and has excellent liquid absorbability. In the non-woven fabric, the constituting fibers are substantially not thermally adhered to each other.
