PROBLEM TO BE SOLVED: To provide an earth anchor that is in a simple shape, can be obtained at low cost, can be buried easily and simply without being affected by density in the ground nor the amount of pebbles included in the ground, and can impart reinforcing force large enough as bearing force to a structure to be reinforced for a long period after the burying.SOLUTION: An earth anchor is provided with: a disk-like body 1 having a shaft 2 as an impact force reception part at a center part； and a wire fitting part 3 fitted with an anchor wire 12 for connecting a column 11 of a structure to be reinforced and the disk-like body 1 together. Consequently, burying work can be easily and simply performed and sufficient reinforcing force can be maintained after the burying work.SELECTED DRAWING: Figure 3
