の耐食性を向上させる作用も有する。FIG. 1 shows a partial sectional view of the pressing member of the present invention. As shown in FIG. 1, the pressing member 1 of the present invention has a metal plating film 3 formed on its surface containing dispersed fine particles 2 made of fluororesin and having a grain size o of 1 to 10 μm. has been done. Due to the action of the fluororesin fine particles 2 partially exposed on the surface of the film 3, excellent mold releasability with respect to the adhesive can be obtained. Note that the metal plating film 3 is
It also has the effect of improving the corrosion resistance of.
