To provide a ground anchor superior in anticorrosiveness with a ground portion using continuous fiber reinforced wire rods superior in anticorrosiveness and strength and a fixation portion using a material superior in fixing performance for developing the characteristics of them when a bed is a corrosive ground in a hot-spring zone.

A ground fixation length portion of a bunch of continuous fiber reinforced wire rods 20 is formed on a tail side and a tensile fixation portion of a bunch of weather resistant PC steel strands 30 is formed on a head side. A free length portion covered with a sheath is formed in an area including connections between the continuous fiber reinforced wire rod and the weather resistant PC steel strand.
