A color cathode ray tube has stress-absorbing hole patterns in skirt portions of its color selection electrode. Each of the stress-absorbing hole patterns is composed of a plurality of columns of rectangular through holes, and the columns are arranged in a lengthwise direction of the skirt portions. Each of the plurality of columns of rectangular through holes is composed of rectangular through holes arranged in a widthwise direction of the skirt portions. The relationships in shape of the rectangular through holes among outermost columns, columns next to the outermost columns, and remaining columns is optimized in the stress-absorbing hole patterns.
