PROBLEM TO BE SOLVED: To provide a door stopper capable of being inserted into a gap between the bottom of a door and a floor from every direction by the tip of a toe and promoting the efficiency of opening and closing work of the door at a low cost. SOLUTION: The door stopper has an approximately truncated cone shape with a cross-section of a trapezoid or an approximately truncated polygonal pyramid shape, and is provided with a fan-shaped inclined part (2) toward the lower side from the upper side. The bottom is opened to make the circumferential edge as a ground contact section (3). A hollow section (4) is formed in the inside, and the upper part (1) is formed into a plate.
