The 2-pole magnet (10) is arranged to have its center closer toe the phosphor screen (4) than the center of the electrostatic main lens of the electron gun assembly. The value, as calculated by dividing the value of the radial component amplitude of the magnetic field distribution of the 2-pole magnet (10) on the circumference having a radus of the s-size, by the value of the circumferential component amplitude, is 0.86 to 1.38, preferably 0.955 to 1.275.
