Beschreibung
Zusammenfassung:	There is provided a spunbonded non-woven fabric including a fiber including a propylene homopolymer having a melting point of 140°C or more, a polyethylene having a density of from 0.941 g/cm3 to 0.970 g/cm3, and at least one polymer selected from the group consisting of a polymer represented in (I) as described below and a polymer represented in (II) as described below. In the spunbonded non-woven fabric, the fiber includes a sea-island structure, and the percentage of an island phase having a diameter of from 0.12 µm to less than 0.63 µm with respect to an island phase in a cross section orthogonal to the axis direction of the fiber on a number basis is 30% or more. (I) represents a random copolymer of propylene and at least one selected from ethylene or an α-olefin having a carbon number of from 4 to 20. (II) represents a propylene homopolymer with a melting point of less than 120°C, satisfying specific conditions.
