In a color cathode ray tube according to this invention, there are provided a plurality of first elastic supporting members welded to a mask frame to support a shadow mask in a panel and each having a metal plate, and at least one second elastic supporting member each having a metal plate and a washer. The area of a polygon formed on a plane lying at right angles with the tube axis and having apices corresponding to the first elastic supporting members is at least about 1/2 of the area of the substantial quadrangle formed by projecting the shadow mask on said plane.
