The invention provides a color cathode ray tube using a shadow mask capable of avoiding ruptures or cracks during press-working. The shadow mask has an apertured region having color selecting apertures, and an unapertured region which surrounds the apertured region. A skirt portion is bent from the unapertured region in the direction of the tube axis. The shadow mask has at least two inclined surfaces in a boundary portion between the unapertured region and the skirt portion.
