[Means for solving problems]
In order to achieve the above object, the present invention forms a first hole having a predetermined depth by pressing the first drill against one side surface of a plate-like body while rotating the first drill, and then tapers from the tip to a position of a predetermined length. While rotating the second drill on which the shaped enlarged diameter portion is formed, the second drill is pressed against the other side surface of the plate-shaped body to form a second hole, and the second hole is formed on one side surface of the plate-shaped body. In the method of drilling a plate-shaped body that communicates with the first hole and is counterbored by the enlarged diameter portion, the second hole is formed when the enlarged diameter portion of the second drill is counterbored. It is characterized in that it communicates with the first hole.
