The ground anchor (1) has steel strip materials which are provided with two end portions (2-1,2-2) such that the width of the strip materials is larger than the thickness of strip materials. The barb points (5,6) extended with respect to longitudinal direction (L) are formed in the region of V-shaped portion. The end portions of ground anchor are opened respectively by partially cutting and bending the barb points at specific angle with respect to longitudinal direction. |
