<p>PROBLEM TO BE SOLVED: To prevent the mulfunction of a pointer by coating a sheet which consists of more than one layer and is provided with a conductivity in at least one layer on the slide part surface of a slide pad. SOLUTION: The sheet which consists of more than one layer or favorably two or three layers and is provided with the conductivity in at least one layer within them is coated on the surface of the slide part 4 of the slide pad 3 so as to execute placement. Thus, even when the slide part 4 is slightly brought into contact erroneously during a normal key operation, it is surely prevented that an unexpected processing is executed and the performance of the slide pad 3 with a high actual feeling and an operability is more improved. Providing the conductivity means that it is equal to below 10Ω.cm, for example. Metal, conductive plastic or conductive rubber, etc., is used as the conductive sheet without any restriction but conductive rubber is faborable by the point of heat radiating property, joining property, an elasticity, heat resistance property and adhesion property, etc., especially. A hardened object with a carbon black and/or silver containing conductive silicon rubber composition is preferable especially.</p> |
