To efficiently embed a screwed type steel pipe pile with a blade having large bearing power.

A spiral blade 5 for screwing, having a broad width and a large diameter extending over the inside and outside of a steel pipe 1, is fixed at the lower end of the steel pipe 1, and a leading cylinder 7 is fixed onto the inner circumference of the spiral blade 5 and provided droopingly. When the steel pipe pile A is embedded at this time, an auger in which a screw having a small diameter is installed to a lower section is inserted into the steel pipe pile A, disposed upright on a ground, and the steel pipe pile A is rotational- pressed in, excavating the ground by the screw.
