摘要： PROBLEM TO BE SOLVED: To inhibit the static electricity or triboelectricity from generating even when the signal electrode is peeled off.
SOLUTION: The surface of the signal electrode 4 is coated with the conductive fluorine resin for forming the conductive film 4a. The signal electrode 4 is provided in the resin lining 3 by lining formation or heat deposition with the lining material. If the signal electrode 4 is pealed off from the resin lining 3, since adhesive force of the resin lining 3 is strong, the conductive film 4a remains on the surface of the resin lining 3. Therefore, if the electrode 4 is peeled off from the resin lining 3 and an interspace may appears inbetween, the surface of the signal electrode 4 and the conductive film 4a remaining on the surface of the resin lining 3 are opposing through the interspace, consequently the static electricity and the triboelectricity become difficult to generate. And also the signal electrode 4 and the resin lining 3 are always the same potential, so even the electrode 4 and the conductive film 4a are brought into re-contact, the potential difference doesn't be generated and the noise becomes difficult to generate.

摘要翻译：要解决的问题：即使当信号电极被剥离时，也可以抑制静电或摩擦电产生。解决方案：信号电极4的表面涂覆有用于形成导电膜4a的导电氟树脂。信号电极4通过利用衬里材料的衬里形成或热沉积设置在树脂衬里3中。如果信号电极4从树脂衬里3脱落，则由于树脂衬里3的粘合力强，所以导电膜4a保留在树脂衬里3的表面上。因此，如果电极4从树脂衬里3和间隙可能出现在其间，信号电极4的表面和残留在树脂衬里3的表面上的导电膜4a通过间隙相对，因此难以产生静电和摩擦电。并且信号电极4和树脂衬里3总是相同的电位，因此即使电极4和导电膜4a被重新接触，也不会产生电位差，并且噪声变得难以产生。版权所有（C）2008，JPO＆INPIT
