Abstract
A first frame includes a bottom portion, an inclined portion, a joint portion and a lateral portion for supporting a shadow mask. Between the lateral portion and the joint portion, a space is provided except where the lateral portion and the joint portion are welded. The joint portion is inclined with respect to the lateral portion such that the space enlarges with an increase in the distance from an edge of the lateral portion on the side of supporting the shadow mask. With this configuration, foreign substances can be removed from between the lateral portion and the joint portion in the process of cleaning the first frame, making it possible to both suppress the deterioration of high-voltage withstand capabilities of a color cathode ray tube and prevent the poor welding of the first frame.
