Abstract

PURPOSE:To obtain a good appearance by integrally bridging a key top member made of thermoplastic resin and a rubber member constituting a leg section. CONSTITUTION:A key top member formed with a composition material made of thermoplastic resin having a vinyl group at the side chain and/or molecular chain end and organic peroxide at the temperature lower than the decomposition temperature of this organic peroxide and an unvulcanized rubber member com bined with this organic peroxide for bridging rubber material with an unbridged rubber material are inserted into a metal mold. They are then heated to the decomposition temperature or higher of the two organic peroxides and pressu rized. The key top member and rubber member thus formed are integrally co-bridged. The contact face between the key top member and leg member is integrally connected completely. No flaw is thereby applied to the key top member via this machining, the connection face with the leg member is not made shabby, and it has a size precisely matching the shape of the key top filling section.
