PROBLEM TO BE SOLVED: To provide a plug for plugging up a hole left in an unclosed state, which is used for plugging up the hole formed by removing an almost truncated cone-shaped form supporting implement and left in a wall surface after the removal of a concrete form, which is excellent in mountability and weatherability, which can be inexpensively manufactured, and which is suitable particularly for surface-to-surface construction. SOLUTION: An almost truncated cone-shaped main body is composed of a composition of calcium carbonate and polypropylene; a screw part of a separator 9, which protrudes on the bottom surface of the hole 10 left in a concrete wall 8, is received into the hollow part 6 of the main body; and an annular protrusion 4, which is formed on an outer peripheral surface in a position to recede by a predetermined interval from a large-diameter side end surface, is brought into contact with the inner peripheral surface of the hole 10, and locked by its frictional force. Anchoring can be surely performed in a position, where the level of the surface of the concrete wall 8 corresponds to that of the large-diameter side end surface, only by a push-in operation.
