PRODUCTION OF ELECTRODE

PURPOSE:To produce the electrode having high quality by fitting the electrode material formed with a coating having good wettability with a brazing material into the recess of a holder consisting of copper and brazing and integrating the electrode material to the holder by the brazing material in a nonoxidative atmosphere. CONSTITUTION:The metallic coating layer having the good wettability with the brazing material 10 is formed on the surface of the electrode material 3 having excellent discharge characteristics. The holder 2' consisting of the copper or copper alloy is provided with the recess (fitting hole) 5 into which the electrode material 3 fits and a fine hole 7 which communicates with the outside therefrom. After the electrode material 3 is fitted into the recess 5, the electrode material 3 is brazed and integrated to the holder 2' in the nonoxidative atmosphere by using the brazing material 10 having the brazing temp. below the m.p. of the holder 2'. The joining degree of the electrode material and the holder is enhanced in this way.
