PURPOSE: The cathode ray tube(CRT) improves the effect of blocking a harmful electromagnetic wave. CONSTITUTION: The cathode ray tube includes; a panel(20) having a screen plane; a funnel(30) including a cone part(32) and a neck part(31) and being confronted with the panel; an electron gun inserted to the neck part of the funnel; an outer conductive film(40) including a first conductive film part(41) coated continuously partially on the outer circumference of the cone part and the neck part of the funnel and a second conductive film part which is coated on the outer circumference of the funnel, being connected with the first conductive film part electrically; a deflection yoke(50) which has a vertical deflection coil, being installed on the cone part of the funnel; and an insulation part which insulates the first conductive film part, being attached on the bent part of the vertical deflection coil. The cathode ray tube absorbs and blocks the electromagnetic wave, which is generated from the deflection yoke coil, with the first conductive film part.
