PURPOSE: To provide a cathode-ray tube which has excellent electromagnetic shielding property and reflection preventive property stable over a wide wavelength range by forming a specified film having fine unevenness in itself, using the specified transparent film on the surface of the panel. CONSTITUTION: An SiO2 film 11 1000Åthick containing 1-20% fluorine with surface resistance of 3×10<3>Ω/port, is made on the outer surface of panel glass 10 by a CVD method. Next, and ethanol solution containing SiO2 is blown against the film 11 to form an SiO2 film 12 having fine unevenness. Hereby, excellent electromagnetic shielding property and excellent electromagnetic shielding effect of light with low refractive index can be gotten, and also excellent reflection preventive property can be gotten by enlarging the diffuse reflection of the light from outside and lessening the regular reflection.
