BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a leather capable of transmitting heat and electric currents and electric signals, and more particularly, The present invention relates to a leather which is capable of easily producing a leather product having convenience functions and capable of transmitting a current and an electric signal.

Leather, which is widely used due to its luxurious texture and appearance, is divided into natural leather processed using animal skin layers such as sheep, cow and pig as raw materials and artificial leather formed with organic synthetic resin layer on the base layer.

Natural leather, like skin, is excellent in breathability and sweat absorbency, and has a high quality of texture, but it has disadvantages that it is difficult to obtain raw materials and it is relatively expensive. Artificial leather has similar physical properties to natural leather, but it has the disadvantage that the raw material can be easily obtained and the price is cheap, but the breathability, absorbency, and texture are less than natural leather.

Natural and artificial leather having the aforementioned drawbacks and drawbacks have been widely used for interior materials such as furniture such as sofas and furniture such as sofas, building materials such as interiors building panels, automobile interior materials such as sheets, etc. It is getting wider.

However, the conventional leather as described above is excellent in touch and texture and has an excellent appearance, but has a disadvantage in that the warmth is relatively low and the surface temperature sensitively responds to the temperature of the leather, so that it always has a cold feeling.

Accordingly, in most products using leather, a separate heating device is provided in preparation for the winter season. For example, in the case of manufacturing a seat cover covered with an outer cover material for an automobile seat, a heating element constructed by arranging a heating wire on a fixing frame is provided on the outer surface of the seat before covering the seat cover, or a surface heating element is provided.

As another example, when the handle cover covering the exterior of the automotive steering wheel is made of leather, the leather handle cover is installed after winding the heating line or attaching the surface heating element.

However, as described above, the method of installing a separate heating element inside the leather involves various complicated problems. That is, the skin and the separate heating element must be prepared and assembled and adhered, respectively, so that the increase of the material cost and the manufacturing labor cost is hindered, and the productivity is decreased due to the increase of the manufacturing time and the assembly time.

In addition, since a separate heating element is provided, the overall thickness of the product using the leather is increased, resulting in poor appearance and deteriorating the merchantability. In addition, due to the foreign body feeling caused by the heating element installed inside the leather, .

In addition, since a large amount of harmful adhesive is used for adhesion between the leather and the heating element or adhesion to the mounting part, there is a problem that it causes discomfort due to the generation of the smell of synthetic resin, skin diseases or allergic diseases caused by environmental hormones.
