<P>PROBLEM TO BE SOLVED: To provide an outer cable anchoring structure of a prestressed concrete bridge, which enables an anchoring body to be installed in a space-saving manner, without damaging a cross girder, and which makes the maintenance of the anchoring body easy and inexpensive. Ž<P>SOLUTION: This anchoring body 10, which comprises a rib cast anchor 12 for inserting an outer cable 50 and a precast concrete block 14 placed in such a manner that the rib cast anchor 12 is embedded, is mounted on the bridge-axis-direction one end surface 102a of the cross girder 102 via a filling layer 20. Thus, the anchoring body 10 does not have to be embedded into the cross girder 102. In addition, the precast concrete block 14 is composed of high-strength fiber-reinforced concrete. Consequently, the precast concrete block 14 dispenses with the arrangement of a spiral reinforcement, and becomes greatly smaller than a concrete block composed of ordinary concrete.
