Abstract
In a cathode ray tube having an antistatic film 6 stuck to the front surface of a panel section 1 and a conductive tape 7 for grounding the end portion of the antistatic film 6 to the earth, a silicone adhesive 8 containing a conductive filler having an excellent close contact adhesion to silicon dioxide (SiO.sub.2) is interposed in at least a part of an close contact adhesion portion where the conductive tape 7 is stuck to the antistatic film 6. Thanks to the interposition of the conductive filler containing silicone adhesive 8, the resistances between the antistatic film 6 and the conductive tape 7 and between the silicone adhesive 8 and the conductive tape 7 can be lowered and sputtering which may be caused by the high voltage induced in the antistatic film 6 is prevented, so that the breakage of the antistatic film 6 can be prevented at the close contact adhesion portion.
