PROBLEM TO BE SOLVED: To provide a method of manufacturing a high-density, insect- and dust-proof blind net without impairing air permeability. SOLUTION: An unprecedented high-density net, such as a light-blocking net, a partition net, a blind net, a roll-curtain net, or particularly a net for the window screen of a sash, is manufacturable from a woven fabric of a monofilament or multifilaments, by repeating warps and wefts in such a way that a heavy thread (reinforcing fiber) and a fine thread (densified fiber) are combined in a certain ratio, or by weaving the threads into checks so as not to impair air permeability while maintaining strength.
