PROBLEM TO BE SOLVED: To provide the connecting method of a pile head and a footing without welding works on a field and a prefabricated pile used for the method. SOLUTION: The prefabricated pile in which a cylindrical side plate A made of a metal is installed onto the outer circumferential surface of a pile head section is mounted into a ground, an arcuate plate B, to which a plurality of anchor reinforcements 9 are set up previously, is screwed and fixed onto the outer circumferential surface of the cylindrical side plate recessed section 2 so that the top face of the cylindrical side plate recessed section 2 and the top face of the arcuate plate B are brought into contact, and the anchor reinforcements 9 are buried into footing concrete and the pile, head and a footing are connected. Since the anchor reinforcements are installed by factory welding or the like, high quality and stable quality can be obtained, and sure and firm fixing against the tensile force of the anchor reinforcements is enabled.
