PROBLEM TO BE SOLVED: To provide a decorative plug for closing a concrete hole formed by removing a plastic cone from a constructed wall, retaining wall, or the like. SOLUTION: A plurality of press-fitting parts 2 are provided, which are hung down to the lower face of a head formed in a size conformed to the concrete hole. A bite-clamping part 5 hanging with a concentric arcuate face 4 at the lower face center of the head may be disposed instead of the press- fitting parts. The outer peripheral surface and the upper face of the head are formed with moderate unevenness to form the decorative plug with the rough surface.
