PROBLEM TO BE SOLVED: To obtain a nonwoven fabric of high modulus which has excellent strength suitable for a material of construction, a marine material, an industrial material, a building material, etc. SOLUTION: The nonwoven fabric is a filament nonwoven fabric is obtained by three-dimensionally interlacing and integrating constituent fibers and has five or more unevennesses with 0.50-3.33μm diameters in an area of 20×20μm on the surface of a fiber constituting the nonwoven fabric and 60-140 N/5 cm 10% modulus based on 100 g/m<SP>2</SP>weight in the length direction of the nonwoven fabric and 20-40 N/5 cm 10% modulus in the width direction.
