<P>PROBLEM TO BE SOLVED: To provide a method of constructing foundation structure in a structure, capable of increasing coupling force between a foundation member constructed on a pile body and the pile body, capable of enhancing construction performance of the pile body, capable of reducing a construction cost by reducing a diameter of the pile body, capable of enhancing quality of the pile body, by using no stabilization liquid, and capable of enhancing earthquake resistance, horizontal resistance and the like by pseudo-increasing the diameter of the pile body, and the foundation structure. Ž<P>SOLUTION: A plurality of improved grounds 2 are constructed wall-likely in parallel with a space within a soft ground 1, and then the pile body 6 is constructed integrally with the improved ground 2 within the improved ground 2, by an earth drill construction method as a cast-in-place pile construction method.
