PROBLEM TO BE SOLVED: To provide a pile fastening structure which is excellent in workability, in fastening strength, especially in twisting strength on an abutting surface as well as in shearing strength, and in cost efficiency, and to provide a fastener for use in the pile fastening structure. SOLUTION: The pile fastening structure is formed of fixtures 2 to be fastened which each have an outer peripheral surface 2A having irregularity in a pile longitudinal direction, and a fastening fixture 1 consisting of an outer member 1A and an inner member 1B which each are circumferentially divided into a plurality of pieces. According to the structure, the outer member 1A has an inner peripheral surface 1a conforming to the irregularity formed on the periphery at a fastened portion when the mutually opposed fixtures 2 to be fastened are abutted on each other, and bolts 3 are penetrated between the abutting surfaces 2F of the fixtures 2 to be fastened, in a radial direction. Further, penetrating recesses 2C are formed between the abutting surfaces of the fixtures 2 to be fastened, through which the bolts are penetrated, and through holes 4 are formed in the fastening member at locations at which the bolts 3 are penetrated.
