PROBLEM TO BE SOLVED: To obtain an elastic stretchable nonwoven fabric useful as a sanitary material, etc., fine in fiber diameter and excellent in air permeability and uniformity, comprising a mixture of a resin composition consisting essentially of an ethylene/α-olefin copolymer, etc. in a specific ratio. SOLUTION: This elastic stretchable nonwoven fabric comprises a mixture of (A) a resin composition consisting essentially of an ethylene/α-olefin copolymer having 85-95mol% ethylene content, 0.87-0.910g/cm<3> density, 15-200 g/10 minutes melt flow rate, 5-40% degree of crystallization and 0.88-0.93g/cm<3> density and (B) a resin composition containing a styene-ethylene/butylene-styrene block copolymer having 40-200 g/10 minutes melt flow rate and 0.88-0.93g/cm<3> density in the ratio of the component A/B of 90/10-50/50 and has <=10% residual strain after 50% elongation and <=25% after 100% elongation. |
