Abstract
A laminated non-woven fabric and a manufactured article using the laminated non-woven fabric are provided. The laminated non-woven fabric is formed by clamping a fibrous layer B between two of fibrous layer A, wherein the fibrous layer B is obtained by using a fiber melting or softening at 120° C. or less, and fibrous layer A includes a fiber neither melting nor softening at 120° C. or less, in which the fibrous layer A and the fibrous layer B are integrated through point thermal compression bonding, and interlayer peeling strength between the fibrous layer A and the fibrous layer B ranges from 0.3 Newton (N)/25 millimeters (mm) to 4.0 N/25 mm.
