Abstract
An entry board for drilling improves drill machinability such as hole positional accuracy using a fine-diameter drill, and roughness of the walls of the drilled holes. The entry board has a metallic foil, and a thermosetting resin is covered on one or both sides of the metallic foil to provide a drill-penetrating layer.
