平４−８６２５６号、実開平２−４７０号）。If a relatively thin film made of the above silicone rubber and having a relatively small thickness is to be directly incorporated into an electric or electronic component, wrinkles may be formed on the thin film, or the thin films may be combined with each other. There was a problem in workability such as adhesion and difficulty in peeling. Therefore, in order to solve such a problem, a laminate in which a silicone rubber alone and a non-stretchable metal sheet are combined and integrated is known (for example, JP-A-4-86256, JP-A-2-470). ).

がやり難いという問題がある。As a method of the composite integration, a method of placing a silicone rubber sheet on at least one surface of a thin metal plate and applying heat and pressure is usually performed. If the metal sheet is difficult or has irregularities on the surface of the metal sheet, there is a problem that it is difficult to bond the metal sheet uniformly. Therefore, a metal composite in which a silicone resin layer is formed by an injection molding method has been proposed. Although this method can improve production efficiency, it is difficult to form an accurate silicone resin layer due to burrs generated by injection molding, and in the case of a fuel cell separator, it is necessary to replace or remove defective parts from the obtained separator. There is a problem that it is difficult to do.
