Problems solved by technology

[0020] Furthermore, although wristbands or glove-type antistatic tools using stretchable conductive fibers rarely cause the above-mentioned problems, they cannot sufficiently solve the problems of dermatitis or residual pressure marks.

Abstract

This invention provides an antistatic tool which, even when the surface form is complicated as in the human body, can realize good adhesion and can effectively remove charges electrified on its surface. A wristband-type antistatic tool suffers from a problem that, when it is fixed for a long period of time, for example, rashing derived from sweating, rashing derived from metal allergy, discomfortcaused by compression, and tightening mark occur in a wrist of a worker. The antistatic tool comprises a support member, an electroconductive layer provided on at least one face side of the support member, a terminal part which has a guard part at its lower end and extends through the support member so that the guard part comes into contact with one side of the electroconductive layer, a coveringlayer for covering the whole lower face of the guard part, and an electroconductive pressure sensitive adhesive layer stacked on the covering layer and the electroconductive layer. The antistatic tool is applied directly to the skin and is brought into intimate contact with the skin by the adhesive power possessed by the electroconductive pressure sensitive adhesive. Accordingly, the adhesion is not influenced, for example, by the difference in skin conditions between individual humans and the difference in physical condition-derived skin conditions, and continuous adhesion to the skin can beensured.

Description

technical field [0001] The invention relates to an antistatic appliance. More specifically, the present invention relates to an antistatic device that can adhere well even to complex surface shapes such as the human body and can effectively remove charges on the surface. The antistatic tool of the present invention is used as a tool for preventing workers from being charged with static electricity in the operation of semiconductor devices, circuits mounted on semiconductor devices, information recording equipment, etc., dust treatment, and chemical substances such as organic solvents. is useful. Furthermore, the antistatic tool of the present invention is useful for operations such as handling of hard disk drives or finer semiconductor devices in a working environment such as a clean room where fugitive dust is particularly prohibited. Background technique [0002] As we all know, static electricity charged by the human body can cause various problems. [0003] For exampl...
