Abstract
BVM coils for modulating a scanning velocity in a horizontal direction of electron beams emitted from an electron gun are provided at a position where the BVM coils are overlapped with an electron gun in a tube axis direction, and a pair of magnetic substance pieces are provided at a position where the pair of magnetic substance pieces are overlapped with the BVM coils in the tube axis direction. The pair of magnetic substance pieces surround a funnel continuously in a circumferential direction of an outer circumferential surface of the funnel, except for a portion of the surface that intersects a plane defined by the tube axis and a vertical direction axis, and the vicinity of that portion. Because of this, a cathode-ray tube apparatus with the sensitivity of the BVM coils enhanced can be provided.
