PROBLEM TO BE SOLVED: To provide a reinforcing cage, a construction method of a cast-in-place concrete pile, and the cast-in-place concrete pile, which are suitable for the construction of narrow railroad facilities with a low restricted space, which can bring about the facilitation of the manufacture of a reinforcing cage, a reduction in weight and the downsizing of a working machine, which can prevent the rapid and safe suspension of the reinforcing cage and sedimentation by slime, which can rationally remove the slime with high accuracy and efficiency, which can bring about the reliability of the construction and stable pile bearing capacity, and which can adapt to the construction of a higher-rise building. SOLUTION: In this reinforcing cage 4 in which a plurality of main reinforcements 5 and a hoop tie 6 are formed in a cage shape, a bottomed tubular cover 7 is provided on the side of one end of the reinforcing cage 4. The main reinforcement 5 and the hoop tie 6 are made of a reinforcement or a carbon fiber. The hoop tie 6, which is obtained by molding a carbon fiber strand, is bonded to the main reinforcement of the carbon fiber strand, and the main reinforcement and the hoop tie are impregnated with an adhesive.
