A frame for use in a color selection mechanism of a cathode ray tube, the frame having a pair of mutually opposing supporting members that has fixedly mounted thereover a color sorting electrode thin plate and elasticity-imparted members each bridged over the corresponding one ends of the supporting members. The frame has a welding gas degassing vent hole that is formed at a position of the supporting member at which the elasticity-imparted member is welded thereto. As a result of this, it is possible to prevent the occurrence of the problems that, after the assembly of the cathode ray tube, the welding gas, the rustproofing oil, etc. are oozed, shot blast balls remain to exist, etc. It is thereby possible to provide a frame for use in a color selection mechanism of the cathode ray tube wherein any defects are prevented from occurring in the tube, such as deterioration of the characteristics, abnormal discharge, etc.
