Abstract
To provide a rugged elastic nonwoven fabric, in which a first fibrous layer containing heat-shrinkable fibers (A) being latent crimp conjugate fibers, and a second fibrous layer containing heat-fusible heat-shrinkable fibers (A) or non-heat-shrinkable fibers (B) both having smaller shrinkage as compared with the fibers (A) are laminated, and both of the fibrous layers are partially bonded and united with a number of bonded parts arranged at intervals, wherein a maximum shrinkage development temperature of the first fibrous layer is 135° C. or higher, a melting or softening point of a heat-fusible component of the fibers (A) or (B) is 70° C. or higher to 130° C. or lower, the second fibrous layer between the bonded parts is projected in a convex by shrinking of the first fibrous layer, and fibers constituting the first fibrous layer are not bonded with each other.
