PROBLEM TO BE SOLVED: To obtain the subject composite yarn net not causing a yarn slippage, having excellent shape retention and wind pressure resistance, useful for a screen door, etc., weaving a thermally bondable composite yarn having a specific fineness in a fixed scale of mesh and making the bond strength of thermally bonded part have a given value or higher than it. SOLUTION: A thermally bondable composite yarn having 200-2,500 dtex, >=1.5 CN/dtex strength and >=10% yarn diameter retention ratio when 40N load is applied to the yarn at a right angle in the direction of the length of the yarn is used as warp and weft, woven in 0.5-5 mm scale of mesh and thermally bonded at intersections of the composite yarn to give a composite yarn net having >=20 CN bond strength. The bending resistance of a net in the direction parallel to the fold of the pleated composite yarn net is >=130 and the length between the peak of the valley of the fold is 5-100 mm. Preferably the thermally bondable composite yarn a composite yarn composed of a low-melting resin and a high-melting resin having >=10 deg.C melting point difference.
