摘要： PURPOSE:To obtain an inner conductive film with degassing characteristics that will not cause any practical problem even at a low exhaust heating temperature by specifying the allowable range of particle diameter of the inner conductive film component material. CONSTITUTION:The inner conductive film of a cathode-ray tube is condensed with the high conductive material containing graphite with an average particle diameter of 1 to 5mum and the low conductive material with an average particle diameter of less than 0.3mum. As a result, a cathode-ray tube with an inner conductive film free of the deterioration of the degree of vacuum at operation even at high resistance and low exhaust heating temperature, can be obtained.
