In the optical fiber composite overhead ground line 1 formed by twisting a plurality of overhead ground wires 4 around the optical fiber unit 2, the optical fiber unit 2 at the end thereof is exposed in a protruding state than the overhead ground wire 4 and the metal pipe 3. At the same time, an internal gripping sleeve 21 is inserted between the aerial ground wire 4 and the metal pipe 3 in an externally fitted state on the metal pipe 3 at a position halfway drawn in from the ends thereof, and the inner gripping sleeve 21 is inserted between the overhead ground wire 4 and the metal pipe 3 in a state of fitting around the metal pipe 3. A compression sleeve 22 for gripping the aerial wire between the inner gripping sleeve 21 and the inner gripping sleeve 21 is fitted onto the outside so as to extend back and forth, and the compression sleeve 22 has a pulling fitting 24 at its tip. The tube 25 is removably provided to accommodate the exposed optical fiber unit 2, and the compression sleeve 22 has its diameter reduced at the portions disposed before and after the internal gripping sleeve 21. 1. A tension end structure of an optical fiber composite overhead ground wire, characterized in that the overhead ground wire 4 is in a bent state by an optical fiber composite overhead ground wire 22a.
