As shown in the drawing, the tin 12 is simply plated on a predetermined conductor (for example, copper) 10 according to a predetermined process. When only the tin 20 is plated on the copper conductor 10 as described above, the conductor is used. It was not enough to strengthen the cold resistance and heat resistance.

In other words, the electrical characteristics of the long-term use is lowered, and the stability and reliability are lowered, the insulation characteristics are not provided completely when the electrical and electronic equipment is used, the error of the device occurs, and the economic losses are increased accordingly.

Therefore, although an insulating material having excellent insulation is plated on the outside of the conductor, a wire having such insulating properties also has a problem of lacking electrical characteristics due to frequent temperature fluctuations caused by the use of electrical and electronic equipment.

Therefore, the present invention by special coating treatment of polyimide (polyimide) and polyamideimide (double imide) to the conductor provided in the wire, thereby strengthening the electrical properties, to ensure stability and reproducibility of electrical and electronic equipment Its purpose is to provide a wire and a method of manufacturing the same to improve the quality of the.

A wire for achieving the above object is a wire having a conductor formed with a coating layer on a predetermined material and an insulator covered on the outer circumference of the conductor, wherein the coating layer has a predetermined heat resistance standard outside the conductor 100. Eggplant is characterized in that the polyimide and polyamideimide are sequentially coated by a polyesterimide over coated polyamideimide copper coating (Polyesterimide over coated polyamide imide coating).

In addition, the wire manufacturing method for achieving the above object, the step of forming a conductor (conductor), the step of sequentially coating the polyimide (polyimide) and polyamideimide (polyamideimide) on the outer periphery of the conductor and , A silicone resin which is a thermosetting resin formed on the outer surface of the coated conductor, a fiber braiding member knitted on the outer surface of the silicone resin 110, and a silicon coating part formed to make a coating on the outer surface of the fiber braiding member.
