Abstract: PURPOSE:To obtain an impregnation type cathode with good electron emission characteristics without requiring special resistance to oxidation treatment or non-oxidation sealing by providing an overlapped thin film consisting of osmium film and ruthenium film or ruthenium-iridium alloy film on the surface of the cathode. CONSTITUTION:A thin film layer 8 made of Os and a uppermost layer 9 made of Ru or Ru-Ir are provided on a cathode pellet 1. The total film thickness is 100- 1,000nm. Since said uppermost layer 9 is hard to oxidize, special resistance to oxidation treatment or non-oxidation sealing that seals a bulb is not required.
