せることが難しい。2. Description of the Related Art Silicon rubber is used as a conventional contact rubber to provide a click feeling and a soft elasticity. When the key top portion of the organic resin is fixed to the silicone rubber, it is difficult to chemically bond the organic resin to the silicone rubber, so that one is fitted physically to the other. In addition, an organic resin can be chemically bonded to the contact rubber using another organic synthetic rubber instead of the silicone rubber, but it is difficult to give a click feeling.

る。According to the present invention, a contact rubber formed and processed with silicone rubber is chemically activated by irradiating a short-wavelength ultraviolet ray to a surface of the contact rubber to break a SiO bond.
We found that a large amount of hydroxyl groups or carbonic acid groups were generated and that thermosetting or UV-curable epoxy resins could be easily chemically bonded, so that resin key tops could be integrated in less steps in less time. Things.
