<p>A non-woven fabric regulated so as to permit swift migration of given liquid. The non-woven fabric is produced by blowing a fluid composed mainly of a gas onto fiber web (100), supported from its inferior surface side by a given air-permeable support member, from its superior surface side to thereby migrate fibers (101) constituting the fiber web (100). In the non-woven fabric, multiple groove portions (1) and convex portions (2) are formed in the direction of extension of blown region, and the fiber density at the groove portions (1) being regions blown by the gas is lower than the fiber density at the convex portions (2) being regions not blown by the fluid composed mainly of a gas.</p>
