PROBLEM TO BE SOLVED: To provide the connection structure of a pile and a post reducing a bending moment in the connecting section of the pile and the post while easily arranging bars accurately without a congestion in the connection structure of the reinforced concrete-constructed pile and post. SOLUTION: In the reinforced concrete-constructed pile 1 and the post 2, upper and lower sections are connected by steel pipes 3 buried and fixed in the concrete of the pile 1 and the post 2 while the end sections of footing beams 8 are connected at the central sections of the steel pipes 3. The connecting section of the pile 1 and the post 2 is constituted so that the upper end of the bar 1a for the pile 1 and the lower end of the bar 2a for the post 2 are separated without a connection, and the connecting section of the pile 1 and the post 2 is formed on a connecting section 9 connected by a short-pipe section at the central section of the steel pipe 3. The connecting section of the pile 1 and the post 2 is further constituted so that the bending moment on the pile-head section side in the case of the occurrence of an earthquake is reduced by the ductility of the short-pipe section of the steel pipe 3 while the bar arrangement works of the pile 1 and the post 2 are conducted easily and accurately.
