PROBLEM TO BE SOLVED: To provide a pile core position confirmation method capable of accurately and easily confirming the core position of a pile before and after installing the pile by using an existing tool. SOLUTION: Length inspection bars 4 are attached to the pile core 1 at two positions in the directions at right angle to each other, respectively. A relief core 2 is formed at the end of each length inspection bar 4. To secure the direction of the length inspection bar 4, one or relief cores 3 are formed between the relief core 2 and the pile core 1 at positions where the relief core 3 is brought into contact with the length inspection bar 4. A pile 5 is set to the pile core 1, and the length inspection bars 4 are set horizontal and brought into contact with the pile core 5 while aligning with the relief core 2 for confirming a pile core first position.
