PROBLEM TO BE SOLVED: To provide a nonwoven fabric having excellent elasticity and flexibility, and suitable for the base cloth of a poultice or the like. SOLUTION: This nonwoven fabric contains, as polymer components, (A) a polybutadiene block containing a vinyl bond of <=30 wt.% and (B) a hydrogenated diene polymer consisting of a conjugated diene block copolymer which contains (i) a polymer block of a conjugated diene having a vinyl bond of >30 wt.% or (ii) a random copolymer block of a conjugated diene containing a vinyl aromatic compound of <50 wt.% and having a vinyl bond in the conjugated diene component of >30 wt.%, and a vinyl aromatic compound. In the above conjugated diene block copolymer, the double bond of the conjugated diene component is saturated in >=80 wt.%.
