縁抵抗を所定の範囲に定めている。2. Description of the Related Art Today, materials such as synthetic resins, synthetic fibers and synthetic rubber are used to manufacture clothing and shoes. However, these materials are highly insulating materials, so static electricity naturally occurs during wearing. However, various problems occur when the static electricity sparks. For example, destruction of electronic components by a spark in an electronic device manufacturer, or discomfort such as a shock on a human body when sparking is cited.
In order to solve such a problem, various antistatic shoes having a conductive sole are conventionally used (for example,
Jikken 7-15443). On the other hand, JIS defines the insulation resistance within a predetermined range.

ことができる。As shown in FIG. 4, the elongated conductive portion 23 of the insole 20 has a conductive cloth 13 (contact portion 14) of the insole 10.
And the conductive cloth 35 (contact portion 33) of the midsole 30 are in contact with each other only partially. On the other hand, since the elongated conductive portion 23 of the insole 20 is composed of the thin conductive threads 21 and 22, the resistance of the elongated conductive portion 23 is different from that of the other layers 10 and 3.
It is set to a value larger than the resistance of 0 and 40. Therefore, the resistance of the antistatic shoe 1 can be set by setting the positions of the contact portions 14 and 33 in FIG. 4 and setting the effective length L of the elongated conductive portion 23. As a result, a predetermined insulation resistance value can be easily set, such as eliminating the need to prototype a large amount of rubber composition to fabricate the outer sole 40.
