Abstract (en)
An object of the invention to provide a melt-blown nonwoven fabric having superior bulkiness and flexibility attained by means of a nonwoven fabric consisting of thermoplastic fine fibers having a fiber diameter of 20 mu m or less spun by a melt-blowing method, characterized in that huge interstitial layers having a width of 30 to 200 mu m and a length of 50 to 30000 mu m which contain no fiber present or which are mostly occupied by spaces if fiber(s) being present are distributed as plural layers in a cross-section of the nonwoven fabric, and that the said interstitial layers occupy 10 to 85% of a total area in an optional positional cross-sectional area having a cross-sectional area of at least 0.25cm<2> in the nonwoven fabric. <IMAGE>
