The brazing material (between the copper plate lead-out lead) is protected by the auxiliary member so that the copper strips are not melted until the copper plate lead-out lead, which is the thick plate side, becomes hot and fits in. Further, since the plasma arc has a high heat concentration property, the above-mentioned action is efficiently promoted.

１およびカーボン板６を相互に確実に密着させる。The copper plate lead lead 2 is set on the ground electrode 3.
On top of that, the copper strip 1 is set so as to be displaced from the side end portion of the copper plate lead lead 2 by the width required for bonding, and the brazing material 7 of the strip (for example, 0.2 mm Bcup-5 in thickness) is placed between them. Sandwich. Further, a carbon plate 6 is overlaid on the copper strip 1 so as to match the end of the copper strip 1, and pressure is applied from above the carbon plate 6 by a pressure press 10, and the copper plate lead lead 2, brazing material 7, copper strip 1 and The carbon plates 6 are surely brought into close contact with each other.
