Provided is a spunbonded nonwoven fabric comprising a core-sheath composite fiber having a core part composed of a core component containing a propylene-based resin (A) satisfying the following (a) to (e) and a sheath part composed of a sheath component containing an ethylene-based resin. (a) [mmmm] = 20 to 60 mol%, (b) [mm] × [rr]/[mr] 2 ‰¤ 2.0, (c) weight average molecular weight (Mw) = 10,000 to 200,000, (d) molecular weight distribution (Mw/Mn) < 4.0, and (e) a melting point (Tm-D), as defined as a peak top of a peak observed on the highest temperature side of a melting endothermic curve which is obtained by holding under a nitrogen atmosphere at -10°C for 5 minutes and then increasing the temperature at a rate of 10°C/min with a differential scanning calorimeter (DSC), is from 0 to 120°C.
