Abstract: A cathode ray tube is provided which includes a panel having a fluorescent surface formed on an inside surface thereof, a tension type shadow mask fitted to the panel with a gap formed therebetween, and a frame. The frame includes two main frames fixed to the tension type shadow mask under tension, and two subframes fixed respectively to ends of the two main frames. A distance between the two main frames between a center part or portion of the main frame and an edge part or portion. To assemble the frame assembly and the shadow mask, the main frames are compressed, the tension type shadow mask is welded thereto, and the compression applied to the main frames is then released. The invention improves a howling characteristic by reducing a vibratory length of the shadow mask and increasing a natural frequency of the center part or portion of the shadow mask.
