Abstract: A spunbond non-woven fabric includes a thermoplastic continuous filament. Bending resistance in a machine direction of the spunbond non-woven fabric is 40 mN or more and 80 mN or less, the spunbond non-woven fabric includes a nonbonded projected part and a bonded recessed part, and in a non-woven fabric cross-section, a thickness from one surface to another surface of the projected part is determined to be tA, a thickness from one surface to another surface of the recessed part is determined to be tB, and respective distances from one surface of the projected part to one surface of the recessed part are determined to be tC and tD (tC

Abstract: A spunbond non-woven fabric includes a thermoplastic continuous filament. A CV value of air permeability of the non-woven fabric is 15% or less, bending resistance in a machine direction of the non-woven fabric is 40 mN or more and 80 mN or less, the non-woven fabric includes a projected part and a recessed part, and in a non-woven fabric cross-section, a thickness from one surface to another surface of the projected part is determined to be tA, a thickness from one surface to another surface of the recessed part is determined to be tB, and respective distances from one surface of the projected part to one surface of the recessed part are determined to be tC and tD (tC
