あった。Conventionally, CRTs used in computer monitors and home televisions have insufficient measures to suppress the transmission of electromagnetic waves, so the damage to the human body cannot be ignored. In addition, because static electricity is generated on the CRT tube surface, dust tends to adhere to the surface, causing static electricity shock to the human body.Also, if the human body is electrically charged while working on electronic circuits, etc., it may cause damage to MO8 semiconductors, etc. There was a problem.
本発明の目的は、これらの欠点を除去するため。 The aim of the invention is to eliminate these drawbacks.
電磁波を十分にシールドし、さらには静電気の発生を防
止するフィルムを提供することにある。An object of the present invention is to provide a film that sufficiently shields electromagnetic waves and further prevents the generation of static electricity.

フィルムは導電性であるから一端を接地して静電気を大
地に吸収しまた磁性体膜を付着されているから外部から
の電磁波をシールドする。Since the film is conductive, one end is grounded to absorb static electricity, and since the film is coated with a magnetic film, it shields electromagnetic waves from the outside.
以下２本発明の実施例を図面を参照して説明する。 Hereinafter, two embodiments of the present invention will be described with reference to the drawings.

止することができる。FIG. 1 shows an embodiment of the film according to the present invention, and shows a cross-sectional view of the film. A magnetic film 2 is produced on the surface of a conductive film 1 by a vapor deposition method or a snow ivy method, and the magnetic film has a magnetic field, and the conductive film has a continuous electric field effect. No, it can prevent the transmission of electromagnetic waves. Therefore, by applying the film according to the present invention directly to the CRT tube surface or to the protective cover of the CRT, electromagnetic interference to the user can be sufficiently prevented.

導体等の破損の防止ができる。Fig. 2 shows the electrical conductivity of the film shown in Fig. 1 by connecting the -7 end of the conductor 3 to one end of the film produced by the vapor deposition method or the suction method or the like at the junction point 4. The other end of the conductor 3 is grounded. Therefore, one can apply the film according to the present invention directly to the CRT tube surface or
By pasting it on the protective cover of the RT and grounding the other end of the conductor, the electrical charge on the CRT tube surface or protective cover will be discharged, and the CR of floating particles such as dust will be discharged.
Adhesion to the T-tube surface or protective cover can be prevented, and electrostatic shock to the human body can be prevented. Alternatively, damage to MO8 semiconductors and the like can be prevented.
