Zusammenfassung:PROBLEM TO BE SOLVED: To realize higher precision in a cathode-ray tube. SOLUTION: Cathode sleeves 31 of cathode bodies KR, KG, and KB are formed of ceramic materials, wherein the cathode bodies organize an electron gun used for a cathode-ray tube. The cathode bodies KR, KG, and KB are arranged on a ceramic board 37 which is formed in one body with spacers 39A and 39B so as to organize a structural body of a cathode 28.
