<p>To provide a rugged elastic nonwoven fabric with high elasticity, high strength and also excellent feeling, in which a first fibrous layer containing heat-shrinkable fibers (1A) being latent crimp conjugate fibers, and a second fibrous layer containing heat-fusible heat-shrinkable fibers (2A) or non-heat-shrinkable fibers (2B) both having smaller shrinkage as compared with the fibers (1A) 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 (2A) or (2B) 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.</p> |
