PROBLEM TO BE SOLVED: To allow a sheet having heat shrinking function before shrinkage to cover an appropriate object to be covered and perform treatment, by which the sheets are strongly bonded with each other, and allow a sheet having heat shrinking function to closely adhere to the object to be covered to make the sheet cover the object to be covered.SOLUTION: An insulative sheet 2 before shrinkage having a heat shrinking function is covered to a copper bar 1, end edge parts 2a to be bonded with each other of the insulative sheet 2 before shrinkage are overlapped, a large number of double clips 3 are attached along the end edge part 2a, and the end edge parts 2a are heated at 100°C to 240°C by an industrial dryer 4 while being pressurized.SELECTED DRAWING: Figure 1 |
