PROBLEM TO BE SOLVED: To improve productivity and to reduce cost by connecting together the sides of adjoining net base bodies through a connecting yarn constituted of the other filament easier bendable than a filament constituting the net base body, and forming a pleat on the connecting part. SOLUTION: The sides of adjoining net base bodies 4A are easily bendably connected together with connecting yarn constituted of the other filament 8 softer than the filament 8 constituting the net base body 4A, and a pleat 6 is formed on the part. Accordingly, even if the net base body 4A is formed out of filament 8 of suitable hardness durable to wind pressure, at opening/ closing operation, smooth bending operation for expansion or contraction is possible. The warp and the woof are crossed by braid and a net 4 having lattice structure of firm combination is formed. Hereby, spreading or cut-off of the network is restrained to propagate, a stable net 4 such as a screen can be formed.
