Disclosed is a color cathode ray tube that can optimize the distance between a spring hole of a spring and a welded junction point and the distance between the junction points with respect to the weight of a mask-frame assembly. The color cathode ray tube includes the mask-frame assembly and a panel that are assembled together by fastening a fixing pin formed on an inner surface of the panel into the spring hole formed on one end portion of the spring of which the other end portion is fixed to the mask-frame assembly directly or through two or more junction points of a spring holder. The cathode ray tube satisfies the condition of 5.0
