The color cathode ray tube without an inner shield, comprising the panel, the funnel, the electron gun and the shadow mask has an inner eletroconductive film electrically connected to the anode cup of the funnel. The electroconductive film is composed of 43-63 wt.% Fe, 36-56 wt.% Ni and 0.38-0.58 wt.% Mn. The film formed on the inner side of the funnel has 0.029 Oe coersive force and 14200 max magnetic permeability.
