PROBLEM TO BE SOLVED: To obtain an insulation operating rod of long life and with high reliability. SOLUTION: The insulation operating rod is provided with a coupling rod charged in high voltage, an insulation rod of a resin laminated body, a connecting pin inserted into the insulation rod in a lamination direction of the resin laminated body for connecting the insulation rod to the coupling rod, and an insulator endowed with a volume resistivity higher than that of the insulation rod along a layer direction, fitted between the connecting pin and the insulation rod, for preventing contact of a layer direction end face of the insulation rod with the connecting pin. Thus, by providing the insulator between the connecting pin and the insulation rod, movement of electric charge to the insulation rod can be delayed to lessen a rising rate of an electric field, so that discharge can be restrained.
