PURPOSE:To obtain a charge/reflection preventing film having sufficient sticking strength in a short time by applying a solution containing polyalkyl siloxane on a face plate end forming a SiO2 film on the surface of the face plate by condensation reaction. CONSTITUTION:A solution containing polyalkyl siloxane is applied to the face plate surface of a cathode-ray tube, and a SiO2 film is formed on the face plate surface by condensation reaction. That is, the solution contains some siloxane bonding from the start in the solution state before being applied to the face plate, i.e., before sintering or drying; thus the film has a strong sticking force even at the stage when the condensation reaction of silanol group is not progressed so much. Accordingly, a sufficient sticking force is obtained under loose calcination conditions (lower temperature or shorter time), and a sufficient charge preventive effect is obtained.
