A voltage applied to the G3 electrode (4) is obtained by dividing with a resistor (10) a voltage applied to the final accelerating electrode (7), and when an electron beam is a non-deflection state, a relationship represented as Va > Vg3 > Vfoc2 is satisfied where Va, Vg3, and Vfoc2 denote voltages respectively applied to the final accelerating electrode (7), the G3 electrode (4) and the second focusing electrode (6). Thereby, the G3 electrode (4) is applied with a high voltage independently for forming a prefocus lens.
