ことを特徴とするカラー受像管の陰極構体。 A cap-shaped cathode base containing a reducing agent is connected to the upper part of the cathode sleeve, an alkaline earth oxide is coated on the cathode base, and a heater is inserted inside the cathode sleeve. In the cathode structure of an in-line color picture tube, in which three cathodes are supported and fixed on respective cathode sleeve supports, and the cathode sleeve supports are supported on the cathode supports and fixed in a straight line, the three cathodes are The cathode sleeve support of the cathode is placed and fixed in the center of the cathode, and the cathode sleeve support is placed and fixed on both sides of the cathode sleeve support, which becomes the welding fixation area between the cathode sleeve and the cathode sleeve support from the lower end of the cathode support. A cathode assembly for a color picture tube, characterized in that the length of the projection from the lower end of the cathode support is relatively short.
