ついて開示がされている。<Prior Art> Conventionally, electrical conductive materials have been used for the socks, insoles, and soles of work shoes worn by workers engaged in electrical work. Regarding the soles, we can embed metal or other conductive materials in appropriate locations to create electrical continuity between the ground and the soles of our feet, or spread metal powder or metal fibers almost uniformly over the entire rubber layer, which is the base material. There are some that are mixed in to provide uniform conductivity throughout the sole of the shoe. Japanese Utility Model Publication No. 54-21144 discloses a conductive shoe sole in which a conductive core, a conductive midsole, and a fabric into which ultrafine copper wires are woven are sequentially laminated on the upper surface of a conductive sole rubber.

なつてしまつた。<Problem to be solved by the invention> If the conductor such as the metal described above is embedded only in a part of the sole, it will not touch the ground when the user stands on his or her toes or only on his heel. There is a risk that electrical continuity between the sole and the sole of the foot may be established. In addition, if metal powder or metal fibers are mixed almost uniformly and in large amounts into the entire rubber layer that is the base material to obtain good conductivity anywhere on the sole, the original flexibility of the rubber will be greatly impaired. It was prone to cracking and had poor wear resistance.

Preferred metal fiber materials include various metals such as copper, iron, and aluminum. Among these, stainless steel is the most preferred because it is resistant to oxidation. The thickness of the metal fiber is preferably 30μ or less so as not to impair the flexibility of the sole material. The fiber length is not particularly limited as long as it can be formed into a web. The reason why the basis weight of the metal fiber web 2 is set to 80 g/ m2 or more in the present invention is that if it is less than that, it will be difficult to manufacture the web, and the web will be damaged when subjected to some stretching action during molding. This is because there is a risk that the tangles of the constituent fibers may be interrupted.
