PROBLEM TO BE SOLVED: To provide a steel pipe pile and its embedding method that prevent a solidified object formed underneath a steel pipe pile while being embedded from becoming insufficient in strength due to mixing of cutting chips or uneven distribution. ! SOLUTION: A steel pipe pile of the invention is installed in a drilled hole 3 formed in a ground 2, and is embedded into the drilled hole 3 with a grout material 9 injected between the pile and a hole wall 5 of the drilled hole. After completion of embedding, an embedded structure is configured for the steel pipe pile comprising a ground improvement body 8 underneath a bottom surface 4. The steel pipe pile 1 comprises a pile main body 6 and a cutter 7 installed on the edge of the pile main body as stirring means, and the cutter is capable of stirring a range equivalent to a transverse cross-section of the pile main body, when rotated around the pile axis. !
