PROBLEM TO BE SOLVED: To provide a columnar structure which has a rational sectional form. SOLUTION: The columnar structure 10 is formed of a cylinder unit 12, a curable filler 14, and stoppers. The unit 12 has a plurality of cylinder bodies 12a to 12e different in diameters. In a pair of first and fifth cylinder bodies 12a, 12e, the lower edge of the first cylinder body and the upper edge of the fifth cylinder body are both blocked. The first cylinder body 12a has its lower edge borne by a base 12f arranged below the same, and its lower end face has an injection port 12g of the curable filler 14 formed therein. When the filler 14 is injected into the cylinder unit 12 from the injection port 12g, the cylinder unit 12 is extended, and then cured in an extended state, to thereby form a columnar form. Then the stopper is arranged between the inner peripheral surface of each of the cylinder bodies 12a to 12e and the outer peripheral surface of the other cylinder body arranged inside the inner peripheral surface. The stopper functions to engage with the inner and outer peripheral surfaces, to inhibit vertical movements of the cylinder bodies, and to prevent the leakage of the filler 14.
