PROBLEM TO BE SOLVED: To give a corrosion-proofing function to a terminal structure by providing a corrosion-proofing rubber cover which is movably put over a protective tube fixed to a bushing section and the peripheral surface of the terminal of a cable in the structure. SOLUTION: A terminal structure is built in such a way that a plug 13 is fixed to the cable conductor 12a of a coupling cable 12 and inserted into an electrode section 11a, and a stress cone 14 is attached to the insulating layer 12b of the cable 12 and pressed against one tapered opening of a bushing section 10. Then pressure is given to a coil spring 17 against the pushing fitting 15 of the stress cone 14 through a washer 16. The coil spring 17, etc., is covered with a protective pipe 18 and fixed to the opening of the bushing section 10 with bolts 19. In addition, a rubber spacer 20 is arranged between the small- diameter section of the protective pipe 18 and the shield layer of the cable 12, and a corrosion-proofing rubber cover 21 is put over the small-diameter section of the protective pipe 18 and the surface of the sheath layer of the cable 12.
