PROBLEM TO BE SOLVED: To provide a construction method for a cast-in-place concrete pile, which eliminates the appearance of a difference of elevation at the upper end of concrete between the inside and outside of a cage in the placing of the concrete, which hardly requires chipping work and the disposal of concrete debris by reducing the amount of the placing of the concrete, and which dispenses with repair costs. SOLUTION: In this construction method for the cast-in-place concrete pile, the inside of the casing 1 inserted into ground is excavated so that the cage 2 can be erected inside the casing 1; subsequently, freshly-mixed concrete A is placed in the casing 1 through a tremie pipe 11 which is inserted into the casing 1; and after the placing of the freshly-mixed concrete A, the casing 1 and the tremie pipe 11 are pulled out. A vibrating motor 19 is attached to the tremie pipe 11, so that the tremie pipe 11 can make vibrations applied to the freshly-mixed concrete A to be placed in the casing 1.
