PROBLEM TO BE SOLVED: To provide a pile head connection structure which exerts sufficient strength against compressive force, pulling fore, and shearing force applied to a pile head, and is produced at a low cost. SOLUTION: According to the pile head connection structure, a steel pipe 4 has both ends 4a, 4b thereof embedded in a pile head 2a of a pile 2 and a foundation 3, respectively, and core reinforcements 5 each have both ends 5a, 5b thereof embedded in the pile head 2a and the foundation 3, respectively, whereby the pile 2 and the foundation 3 are connected together. Herein a gap h3 is secured at a location between the pile head 2a and the foundation 3. The pile head connection structure 1 is applicable to a so-called reinforced concrete pile, and therefore cages 7, 8 are embedded in the pile 2 and the foundation 3, respectively, but main reinforcements of the cage 7 are not anchored to the foundation 3.
