Each mounting hole 8 comprises a counterbore hole part 9 having the same depth as the head 20a of a nail 20 to fit the head 20a therein, a funnel-shaped hole part 10 smaller in diameter than the counterbore hole part 9 and gradually reduced in inner diameter toward the rear face 4 side of the base A for the panel, and a cylindrical hole part 11 having an inner diameter equal to the minimum inner diameter of the funnel-shaped hole part 10 and equal to the outer diameter of a body part 20b of the nail 20.
