The present disclosure relates to a permanent anchor used for suppression of a collapse of cut slopes in a rock or ground cutting area or suppression of a collapse of excavation walls during engineering works and more particularly, to a permanent anchor including a steel wire fixing part (10) for fixing and coupling tension members (110) and an anchoring head part (20) to be expanded and unfolded by a grout injection pressure. The anchoring head part (20) is configured to be coupled to a lower end of the steel wire fixing part (10), and includes a fluid (50) operating by the grout injection pressure and a plurality of anchor wings (60,60') configured to be expanded and unfolded by a pressure applied by the fluid.
