The thin molded article of the present invention includes a thin flat plate 1 and dam/discharge ribs 6 provided on the thin flat plate having a shape in which bar-type ribs having wide or large diameters extend radially from the center of the molded article. The tips of the bar-type ribs having wide or large diameters have a shape that allows the molten resin injected from a gate into a cast to be accumulated temporarily before it flows into said thin plate, thereby providing a configuration in which the tips of said ribs do not reach the outer edge of the molded article.
