To prevent a structure as a base body from being broken and handle an anchorage body as a unit body while reducing the number of anchorage operations in the anchorage body installed at the end of a structure in the exposed state to the end face of the structure such as a concrete and used for anchoring a tendon for introducing a prestress to the structure.

The tendon 7 for introducing the prestress is inserted into the structure 9. The anchorage body 1 comprises a cylindrical guide 2 receiving the anchorage material 5 for anchoring the tendon 7 on the end face of the structure 9, and a block 4 formed of an inorganic material in which the guide 2 is buried and reinforcing fibers are mixed, or comprises the guide 2, a reinforcing material 3 disposed around the guide 2, and the block 4 formed of the inorganic material in which the guide 2 and the reinforcing material 3 are buried. A compressive force and a tension from the tendon 7 transmitted from the guide 2 in the structure 9 are received by the block 4.
