PROBLEM TO BE SOLVED: To offer a fixing structure of a utility pole made from aluminum alloy pipe to the foundation, which has a strength to the same degree as a fixing structure of the utility pole made from a steel pipe, is structured simple, and can reduce the time and staff for executing the fixing operations. SOLUTION: A flange 121 made of aluminum alloy is fixed to the bottom of a utility pole 111 made from an aluminum alloy pipe, and a anchoring metal 151 consisting of a vertical pipe portion 161, a flange part 171 fixed to the bottom of the vertical pipe portion, and a plurality of reinforcing ribs 181 installed between the peripheral surface of the vertical pipe portion 161 and the top surface of the flange part 171 is fitted on the utility pole 111 so that a double structure is accomplished, and therein the flange 121 of aluminum alloy is fixed to the foundation Fd by a nut 20 and anchor bolt 19 implanted therein Fd together with the flange part 171 of the anchoring metal 151 contacting with the oversurface of the flange 121.
