PURPOSE:To prevent solder for adhesion from being sucked up between divided target pieces and to improve the cooling efficiency for a target body by chambering the end faces of said pieces intersecting with the adhesive surfaces to a cathode electrode. CONSTITUTION:The target pieces 14 which are divided to plural pieces are arrayed on the cathode electrode 11 in such a manner that the side faces thereof contact each other. The end faces of the pieces 14 where the adhesive surfaces to the electrode 11 and side faces intersect are chamfered 15 prior to the arraying. The pieces 14 and the electrode 11 are then adhered by the solder 13 for adhesion. |
