    Abstract: A cathode material of an electron beam device comprising 0.5 to 9.0 % by weight of a rare-earth metal of the cerium group, 0.5 to 15.0 % by weight of tungsten and/or rhenium, 0.5 to 10 % by weight of hafnium and the balance of iridium is provided. Since the cathode material has excellent plasticity, it is easy to manufacture small-size emitters. Also, since the density of the electron emission of the cathode material is high and the working temperature is low, a long lifetime can be ensured. Also, the cathode material is useful as a cathode material of an electron beam device.
