This power feeding brush uses a conductive wire made of phosphor bronze or titanium. As shown in FIG. 6, the conductive wire 1 is flocked on one surface of the flat base member 2 as a band-shaped group ( Since the conductive wire 1 is very thin, it is expressed as flocking.).

定的に生産する上での障害となっている。This power supply brush needs to have appropriate flexibility so as to appropriately contact the object 3 to be processed, and therefore the conductive wire 1 is formed to be long to some extent. As a result, it is difficult to implant and attach the power feeding brush, and a slight error in the attachment position causes a problem such as scratching the object to be processed. In addition, the conductive wire 1
Since it is easy to break, frequent replacement is required, which is an obstacle to stable production of the object to be processed.

ラシを用いなければならない。From the viewpoint of the material of the conductive wire 1, there are problems both when phosphor bronze is used and when titanium is used. When phosphor bronze is used, there is a problem that the material is poor in corrosion resistance, but flexibility can be dealt with by lengthening the hair. However, if the mounting is not performed with a high dimensional accuracy, the flexibility is deteriorated or the wear is increased. Further, when titanium is used, it has poor flexibility and followability, is not elastic, and is easily broken, and has insufficient current-carrying performance. Therefore, a large number of power-feeding brushes must be used to secure the current-carrying performance.

As a result, there is a problem that it is highly consumed and frequent replacement work is required.
