Zusammenfassung:	PURPOSE:To provide a non-woven fabric having an excellent strength in one direction and suitable for a construction material by drawing a web comprising continuous filaments with a drawing device in the direction of the flow of the web. CONSTITUTION:The objective non-woven fabric is produced by drawing a web comprising continuous filaments such as polypropylene filaments with a drawing device in the direction of the flow of the web preferably up to the maximum drawing ratio of 4 times. It is preferable that the web has a single filament fineness of 1-20 denier, a weight of 15-600g/m and a longitudinal/lateral tensile strength ratio of 0.8-5.
