PROBLEM TO BE SOLVED: To reduce cost while securing enough fitting strength between a spiral blade part and a straight pipe-like part by integrally forming the spiral blade part and the straight pipe-like part to eliminate the need of welding work. SOLUTION: This end member 50 fitted to a pile is formed by including the cylindrical straight pipe-like part 51 and the spiral blade part provided at the ground side of the straight pipe-like part, and integrally casing the straight pipe-like part and the spiral blade part 52. The spiral blade part 52 is extended in the inside and outside directions of the straight pipe-like part 51, and in the inside of the straight pipe-like part 51, an opening is reduced to be half-blocked. The vicinity of the end on the opposite side to the blade part in the straight pipe-like part is provided with a plurality of through holes 55, and a connector is inserted in the through holes 55 and a through hole provided in the pile to make connection.
