Shadow mask in a color CRT including an electron reflective film formed, starting from a surface of the shadow mask, down to an inside surface of each of holes, or an electron reflective film formed on a surface of the shadow mask facing an electron gun, or on the surface of the shadow mask and an inside tapered surfaces of holes of the shadow mask and another electron reflective film formed on a surface of the electron reflective film formed on the shadow mask facing an electron gun, thereby reducing thermal deformation of the shadow mask, with a consequential reduction of doming, that prevents mislanding of the electron beams, color dispersion of the color CRT, to improve a color purity.
