PURPOSE:To prevent generation of sparkle so as to obtain an image of high quality, by using combined substance comprising unsaturated polyester as the main agent of adhesive, styrene or one kind of styrene derivant as bridging agent and one kind of unsaturated ester as another bridging agent, in a cathode ray tube in which a glass plate is attached to the front face of a face plate part via an adhesive. CONSTITUTION:Non-reflective glass 4 is adhesively set on the front face of the face plate part 2 of a cathode ray tube body 1, by means of an adhesive 3' made from unsaturated polyester resin including about 70wt% of unsaturated polyester serving as main agent, about 20wt% of styrene serving as the first bridging agent and about 10wt% of unsaturated ester serving as the second bridging agent. Since any difference in refractive index between main agent and bridging agent is eliminated by using an adhesive of such composition and sparkle can be certainly prevented from being generated, an image of high quality can be attained.
