Abstract
In a method of manufacturing a contact rubber structure, colored, hard, non-vulcanized rubber materials are injected into cavities of a mold for molding key top portions. A mold for molding key sheet portions is placed over the key top portions formed by the foregoing molding step. A non-vulcanized rubber material which is softer than the material of each key top portion is charged, compressed and heated, so that the key sheet portions are made to be integral with the key top portions.
