A METHOD FOR MANUFACTURING ELECTRODES OF AN ELECTRON GUN FOR A CATHODE RAY TUBE AND ELECTRODES MANUFACTURED THEREBY ARE DISCLOSED. THE METHOD FOR MANUFACTURING ELECTRODES OF AN ELECTRON GUN FOR A CATHODE RAY TUBE COMPRISING THE STEPS OF PREPARING A FIRST ELECTRODE MEMBER (41) HAVING BEAM PASSING HOLES (45), THE CIRCUMFERENTIAL PORTION OF WHICH HAS A PREDETERMINED THICKNESS, AND GAS EXHAUST HOLES (44); PREPARING A SECOND ELECTRODE MEMBER (42) HAVING A FLAT PORTION (51) WHICH HAS THROUGH HOLES (47) FORMED TO BE LARGER THAN THE BEAM PASSING HOLES AND ANOTHER GAS EXHAUST HOLES (46) FORMED TO BE THE SAME AS OR LARGER THAN THE GAS EXHAUST HOLES, A SIDE PORTION (52) PERPENDICULARLY EXTENDED FROM THE PERIPHERAL PORTION OF THE FLAT PORTION, AND EMBEDDED PORTIONS (48) PERPENDICULARLY EXTENDED FROM THE SIDE PORTION; AND ALIGNING THE ELECTRODE MEMBERS FOR THE BEAM PASSING HOLES AND GAS EXHAUST HOLES OF THE FIRST ELECTRODE MEMBER TO RESPECTIVELY CORRESPOND TO THE THROUGH HOLES AND GAS EXHAUST HOLES OF THE SECOND ELECTRODE MEMBER, AND WELDING THE ELECTRODE MEMBERS TO EACH OTHER. WITH THE METHOD, THE MANUFACTURE OF ELECTRODES CAN BE PERFORMED WITH EASE, AND, IN PARTICULAR DEFORMATION OF ELECTRODE MEMBERS BY MECHANICAL AND THERMAL STRESSES PRODUCED DURING MANUFACTURING PROCESSES CAN BE PREVENTED.FIGURE 11
