A stretchable nonwoven fabric manufactured by using a hydrogenated block copolymer obtained by hydrogenating a block copolymer including polymer blocks A constituted mainly by a vinyl aromatic compound and a polymer block B constituted mainly by a conjugated diene compound, at least one polymer block B being arranged on an end of a polymer chain of the block copolymer, as a raw material. The spinning property and characteristics of the nonwoven fabric can be further improved by adding a polyolefin to the above raw material. The obtained stretchable nonwoven fabric has a superior strength, extension characteristics, i.e., elongation and extension recovery, and weathering resistance, and can be broadly used for many applications due to those characteristics.
