Abstract

To provide a stretchable bulky nonwoven fabric having a high bulkiness and a good feeling; wherein a first fibrous layer including fibers () is laminated with a second fibrous layer including heat fusible fibers () and having a MD shrinkage ratio lower by 5% or more than a MD shrinkage ratio of the first fibrous layer, the first fibrous layer and the second fibrous layer are integrated by entanglement between the fibers () included in the first fibrous layer and fibers () included in the second fibrous layer, the first fibrous layer is shrunk to form a structure in which the second layer is raised in the thickness direction, and sonic bond processing is applied from a side of the second fibrous layer.
