<P>PROBLEM TO BE SOLVED: To provide a pile head joining structure capable of suppressing the effect of the fluctuation of an axial force in an earthquake by reducing a restricting action by the concrete forming the foundation concrete structure of a building to thereby reduce the fluctuation in the rotational rigidity of a pile head by the axial force, and effective also on an increase in construction efficiency when adapting to each of the pile heads respectively in consideration of the situation of each pile head. Ž<P>SOLUTION: A plurality of steel sleeves 4 are disposed on a pile head end plate 2 in such a manner as to be fitted onto a pile head reinforcement 3, and a steel plate 5 is placed on each steel sleeve 4 so as to cover the upper side of the pile head end plate 2. The interval between the pile head end plate 2 and the steel plate 5 is held with the steel sleeve 4, and the compression load acting on the pile head is shared with the steel sleeve 4 to reinforce the pile head reinforcement 3. In place of the steel sleeve 4, a steel ring is disposed on the inside of the arrangement of the pile head reinforcements 3, and the steel plate 5 is supported with the steel ring.
