    Abstract: PROBLEM TO BE SOLVED: To provide a PC steel twisted wire capable of performing substantially semipermanent antirust as well as excellent high sustainability in comparison to the conventional PC steel twisted wire.SOLUTION: A PC steel twisted wire 10 comprises a synthetic resin coating on a circumferential surface for anticorrosive treatment. The PC steel twisted wire comprises a core wire 8 and a side wire 9, each element wire 1 is subjected to the wire drawing treatment followed by the plating treatment to form a plating layer. Each of the element wires is adjusted under the adjusting conditions (A) to (C) of wire diameter as below and then twisted together. The plating layer serves to cover the partial surface delamination of the synthetic resin coating formed on the circumferential surface or rust proof deficiency due to pinholes. The double rust-preventing PC steel twisted wire thus obtained has a tensile strength of 1850 N/mmor more. (A) core wire diameter: 4.42±0.05, side wire diameter: 4.25±0.05, (B) core wire diameter: 5.22±0.05, side wire diameter: 5.06±0.05, (C) core wire diameter: 5.40±0.05, side wire diameter: 5.25±0.05.
