PURPOSE: An electron gun for CRT is provided to improve the distribution of a focus property by reducing an alignment error among electrodes. CONSTITUTION: An electron gun(10) for CRT comprises a triode including a cathode(12), a control electrode(14), and an accelerating electrode(16); a first anode(18b) arranged next to the accelerating electrode; a focus electrode(20) arranged next to the first anode; and a second anode(22) arranged next to the focus electrode. The electron gun is formed with two or three divisions. The divisions are supported by insulating supporters.
