Abstract
According to a method of producing a key top for a pushbutton switch of the present invention, a base layer made of an insulating resin that can be plated with metal, an electroless plating layer to be formed on the surface of the base layer, and a polymer coating layer, if required, are stacked on the surface of a key top body. Alternatively, an electroplating layer formed by electroplating is further formed on the electroless plating layer. Therefore, a plating layer can be directly and easily formed on the insulating resin, whereby a key top for a pushbutton switch having a sensation of metal and being rich in design is obtained.
