The underbracing for an arch-shaped utility pole of the present invention is molded with just conductive concrete and general concrete since the conductive concrete layer disposed at the lower part of the underbracing for an arch-shaped utility pole is mixed with metal fragments during molding. The conductive concrete layer is connected to the reinforcing steel in the utility pole underbracing, and an additional lead wire is connected to the reinforcing steel. Therefore, the automation facility for an existing underbracing for an arch-shaped utility pole may be applied without changes so that the utility pole underbracing of the present invention can be suitable for mass production, and the error rate of the utility pole underbracing of the present invention may be close to zero so that the utility pole underbracing can be highly economical. The metal fragments in the conductive concrete layer further increase the grounding efficiency fn the conductive concrete layer by having the effect of reducing high grounding resistance, and the grounding efficiency can increase while production costs can be reduced even without using an expensive ground plate because the lead wire is welded directly with the thick reinforcing steel.
