Abstract
PURPOSE: To provide soft elastic material such as sponge having a predetermined uniform thickness by once impregneting the soft material with a substance for promoting cooling and hardening such as water and thereafter cutting the impregrated soft elastic material.
CONSTITUTION: After impregnating a soft elastic material 10 such as sponge with water or the like, the soft material is cooled and hardened. Then, after cutting into a predetermined thickness, the water is removed. For example, in case that movable electrode buffer of keyboard device is made, whole soft elastic material 10 is penetrated with water and therafter cooled to freeze the water in the inside and remove softness. Then after the hardened elastic material 10 is cut into the predetermined thickness, the water is removed and a film of polyester 11 is heat-welded to upper and lower surfaces and a film 12 and conductive film 13 which do not pass through adhesive agent are attached thereon. Then, it is blanked into desired shape and as separating the film 12, can be used as electrode buffer.
