Abstract
A CPU for adjusting color purity and color displacement at the center of a screen is provided on an outer circumferential surface of a neck portion. BVM coils for modulating a scanning velocity in a horizontal direction of electron beams are provided at a position where they are overlapped with the CPU in a tube-axis direction. A ring-shaped ferrite core is provided at a position where it is overlapped with the BVM coils in the tube axis direction. Two surfaces vertical to a tube axis of the ring-shaped ferrite core are covered with resin layers. Because of this, the ring-shaped ferrite core can be prevented from being cracked.
