Summary:PROBLEM TO BE SOLVED: To provide a connection structure, and the like, of a power cable ensuring excellent workability for a high voltage power cable having an aluminum conductor, and allowing a conductor to be gripped in a sleeve reliably.SOLUTION: At first, an insulating coating 6 at the end of power cables 10a, 10b is peeled by a predetermined length, and aluminum conductors 5a, 5b are exposed. Subsequently, the ends of the aluminum conductors 5a, 5b to be connected are inserted from both ends of a sleeve 1. Thereafter, in a state where the aluminum conductors 5a, 5b are inserted into both ends of the sleeve 1, a bolt 7 is inserted into a bolt hole 6. When fastening the bolt 7, the aluminum conductors 5a, 5b can be pressed by the tip of the bolt 7. Thereafter, a part of the outer periphery of the sleeve 1 is compressed along with the aluminum conductors 5a, 5b. Compression parts 9 are formed near both ends of the sleeve 1. The aluminum conductors 5a, 5b are gripped in the sleeve 1 by the compression parts 9.
