<P>PROBLEM TO BE SOLVED: To provide a liquid cooling type hollow wire and an electric machine using the same capable of preventing current leakage. <P>SOLUTION: A plurality of hollow parts 2-1 and 2-2 are formed in a wire 1 which acts as a single wire while electrically integrated. At one end of the wire 1, a cooling liquid is supplied from at least one hollow part 2-2 out of the plurality of hollow parts 2-1 and 2-2. At the other end of the wire 1, the cooling liquid supplied from at least one hollow part 2-2 is returned to the other hollow part 2-1. At one end of the wire 1, the cooling liquid is discharged from the other hollow part 2-1, so that the cooling liquid circulates in the wire 1, for it to be cooled. <P>COPYRIGHT: (C)2004,JPO |
