Abstract

PURPOSE:To impress an anode voltage effectively to desired electrodes in accordance with the ratios of their corresponding resistances by forming a resess in a resistant body at a location near the position where each the desired electrodes is planted. CONSTITUTION:In one unit 22 of supporting units 21 and 22 of an electron gun units, recesses 82-112 are formed in a glass resistor 2a at positions near locations where the 3rd to 6th grid are planted, by removing a glass insulating member layer 2b at the positions. In assembling the electron-gun by the above components, each of the 3rd to 6th grids is directly planted in the glass resistor 2a while the 1st and 2nd grids 6, 7 are planted in the same resistor 2a through the glass insulating member layer 2b. Thereby, an anode voltage may be impressed effectively to a desired electrode in a simple method.
