るようにしてもよい。The non-woven fabric of the present invention is one in which short fibers of copper or copper alloy are evenly distributed on the surface, and the dispersed fibers are pressure-sintered and the intersected portions are sintered. Most preferably, the fiber has a wire diameter of 10 to 50 microns and a length of 100 mm or less. When the short fibers are sprayed and dispersed evenly on the surface, the density ratio is dispersed so as to be approximately 90% or less, and when this is pressed and sintered, the thickness is approximately close to the wire diameter of the short fibers. A non-woven fabric whose thickness can be appropriately adjusted, from a thick to an arbitrary thickness, can be obtained. At this time, the applied pressure is preferably 30 g / cm 2 or more. As the plating metal, gold, silver, tin, nickel, cobalt, and alloy plating of these metals, for example, nickel-cobalt,
Any plating metal such as nickel-phosphorus, nickel-cobalt-phosphorus and the like, which is commonly used for electroplating and electroless plating, can be used. If necessary, composite plating is also possible, and various functions such as magnetic properties can be added depending on the type of dispersed particles. A thickness of several microns to 10 microns is sufficient for these thicknesses. The alloy component of the short fibers may be copper alone or copper (zinc, tin, nickel,
A composition containing up to 5% of one or more elements selected from iron, manganese, and aluminum) is preferable. The pressure sintering atmosphere and temperature are preferably non-oxidizing atmosphere and 650 to 950 ° C. When the short fibers are plated, the sintering temperature is set to the melting point of the plated metal at Tmp. Then, (0.6 to 1.0) Tmp. Is sufficient, and sufficient sintering occurs even if the temperature is not raised to above the melting point of the plated metal. For example, when the plating metal is Ni-P, it reacts with the base copper to form a Ni-Cu-P alloy having a low melting point, and a melt appears at a temperature below the melting point of Ni-P.
When plating short fibers, long fibers may be plated and cut into short pieces, or short fibers may be uniformly dispersed on a plate, and the plate may be dipped in the plating solution as it is to plate. Good.

れていた。The present invention will be described with reference to examples. Example 1 A copper wire having a diameter of 50 microns, which was plated with a Ni-P alloy at a thickness of 8 microns, was cut into a length of 100 mm and made into short fibers so that the density ratio was 90% on a noncombustible plate. 40 g of weight per unit area (cm 2 ) was placed on the powder, and it was sintered at 850 ° C. for 30 minutes in a hydrogen atmosphere. The intersecting portions of the short fibers were completely sintered, and the thickness of the non-woven fabric was about 50 μm, which was extremely flexible. Example 2 Short fibers of a copper alloy having the following composition having a diameter of 30 μm and a length of 80 mm were scattered on a noncombustible plate so that the density ratio was 95%, and a weight of 30 g per unit area (cm 2 ) was applied to this. And was sintered for 30 minutes at 850 ° C. in a vacuum atmosphere. The intersecting portions of the short fibers were completely sintered, and the thickness of the non-woven fabric was about 100 μm, which was extremely flexible. Chemical composition (wt.%) Of the copper alloy short fibers used Cu Sn 95 5 Example 3 Copper short fibers having a diameter of 20 microns and a length of 50 mm were sprayed on a non-combustible plate so that the density ratio was 90%. Then, a weight of 30 g per unit area (cm 2 ) was placed on this, and sintered in a hydrogen stream at 900 ° C. for 30 minutes. The intersecting portions of the short fibers were completely sintered, and the thickness of the non-woven fabric was about 20 microns, which was extremely flexible. Next, this was electroplated with tin to a thickness of 5 μm, and heat-treated in an oxidizing atmosphere to change to tin oxide. The tin oxide surface was extremely excellent in corrosion resistance.
