PURPOSE:To improve lamination and workability in such a way it is made by insulating between the cathode and the anode with ceramic insulating plates by means of joining them in two plies or more. CONSTITUTION:A ceramic insulating plate 1 which contains Al2O3 is interposed between a cathode 3 and an anode 4, and the both electrodes are insulated by soldering them with metallized layers 2 of Mo-W or W. The ceramic insulating plate 1 is made by joining in two plies or more. For example, Al2O3 is put as the main ingredient whereon a binder, etc. is added, which is rolled out to form into green sheet shape on which holes 5 are simultaneously made for penetrating cathodes 3 through by press-machining after it has been cut off in square shapes, and finally it is manufactured by slitting for the purpose of dividing the outer shapes. |
