The purpose of the present invention is to provide a foundation pile which eliminates the need for the restoration work of the thread of a bolt even when the bolt is joined to a spiral pile, and achieves improved corrosion resistance. This foundation pile comprises: a spiral pile (1); a plate-shaped member (4) disposed at the top of the spiral pile (1) so as to form a portion approximately perpendicular to the longitudinal direction of the spiral pile; a bolt (7) disposed to pass through a hole (6) provided in the plate-shaped member (4) from the spiral pile side; and a nut (not shown) screwed onto the bolt so as to sandwich the plate-shaped member therebetween.
