ABSTRACT OF THE DISCLOSURE An electron gun employed in a color cathode ray tube, or the like, adapted, when electron beams are deflected in a convergence free deflecting magnetic field, to achieve optimal focused conditions for both the electron beam landing at the center and that landing at the corners of a screen by making, within a principal converging region for converging the electron beams, the converging angle in the vertical direction smaller than that in the horizontal direction and by forming, within an object point forming region, the object point in the vertical direction at a further position than where the object point in the horizontal direction is formed.
