Summary:PROBLEM TO BE SOLVED: To provide a waterproof treatment structure of a power cable terminal, which absorbs deviation between a corrosion proof layer of a power cable, and a rubber insulating terminal member or insulating connection member when the power cable is bent at the vicinity of the rubber insulating terminal member and the insulating connection member and is excellent in a waterproof characteristic and a low temperature characteristic.SOLUTION: A waterproof treatment part 40 has a structure where a deformation layer 41 (41a and 41b), a shape stable layer 42 (42a, 42b and 42c), an insulating layer 44, a waterproof layer 45 (45a and 45b) and a water shut off layer 46 are laminated. A VUL-CO tape having self-fusion property is wound and the deformation layer 41 (41a and 41b) is formed. A butyl rubber watertight tape is wound and the waterproof layer 45 is formed to cover an end of the insulating layer 44. A silicone tape is wound and the water shut off layer 46 is formed to cover an entire surface of the waterproof layer 45 (45a and 45b) and a surface of the insulating layer 44 which is not covered by the waterproof layer 45.
