摘要： Disclosed is an impregnated cathode structure for a cathode ray tube and its manufacturing method, in which electron emitting material impregnated in a pellet is free from an effect of the welding heat generated when the pellet is secured to a heater sleeve. The impregnated cathode structure has a pellet assembly including a pellet and a pellet fixing sheet. The pellet is attached to a first surface of the pellet fixing sheet, which has a plurality of protuberances. The pellet is manufactured by pressing and sintering, and impregnating electron emitting material into the porous of the pellet. The pellet sleeve is inserted in and welded to a heater sleeve. A heater sleeve is welded to a second surface of the pellet fixing sheet, which is opposite to the first surface.
