PROBLEM TO BE SOLVED: To obtain a nonwoven fabric or the like with a multi-layered structure, and having a large nonwoven fabric strength, and excellent permeability and bulkiness. SOLUTION: This nonwoven fabric has a multi layer structure obtained by laminating a spun-bonded nonwoven fabric of a mixed fiber and a carded nonwoven fabric. The spun-bonded nonwoven fabric of the mixed fiber is obtained by mixing 10-90 wt.% filament with a low melting point, with 90-10 wt.% filament with a high melting point and composed of resins having >=10 deg.C difference of melting points, and subjecting the fiber crossing points to adhere by the heat-fusion of the filaments with the low melting points. The carded nonwoven fabric is obtained from a crimped staple fiber with 25-128 mm fiber length. The spun-bonded nonwoven fabric of the mixed fiber and the carded nonwoven fabric are integrated by the heat fusion of at least one of the filament with the low melting point of the spun-bonded nonwoven fabric of the mixed fiber and the staple fiber of the carded nonwoven fabric. The laminated nonwoven fabric has 80-2000 cm<3> /cm<2> /sec permeability and 15-70 cm<3> /g specific volume. The absorptive article is also obtained by using the nonwoven fabric. |
