PROBLEM TO BE SOLVED: To provide a spunbonded nonwoven fabric soft and favorable in feel such as skin touch and also slight in fluffing, to provide a method for producing such a spunbonded nonwoven fabric, and to obtain absorptive articles each using the above kind of spunbonded nonwoven fabric. SOLUTION: This spunbonded nonwoven fabric is so designed as to have non-fused regions with filaments not fused to one another and fused regions with filaments fused to one another through emboss fuse processing; wherein the fused regions lie zigzag-fashion on the surface of the nonwoven fabric and the filaments among the non-fused regions has <=400 in the numerical value given by the formula (a) shown below and <=150 in the numerical value given by the formula (b) shown below; the 2nd objective method for producing the above spunbonded nonwoven fabric is provided; and the 3rd objective absorptive articles are obtained using the above spunbonded nonwoven fabric. (Lf/2)×sin(Acos(Lm/Lf))...(a), and Lm3/S2×10-3...(b) (Lf is the average length (μm) of the filaments in the non-fused region mutually connecting the adjacent fused regions; Lm is the average length (μm) of the straight lines connecting the shortest distance between the adjacent fused regions and used in measuring Lf; and S is the average cross-section area (μm2) of the filaments).

PROBLEM TO BE SOLVED: To provide a polyolefin nonwoven fabric which holds the original characteristics such as strength or toughness, of a spun-bonded nonwoven fabric made of polypropylene resin, has excellent flexibility, drapeness a touch feeling and the like, and is used for absorbing articles such as disposable diapers, and to provide a use thereof. SOLUTION: This spun-bonded nonwoven fabric comprising a polyolefin resin and having an average fiber diameter of 5 to 60 μm and a METSUKE of 5 to 200 g/m2, characterized by having a coefficient of static friction of 0.1 to 0.4. For example, a spun-bonded nonwoven fabric containing a lubricant (a fatty acid amide compound).
