A film type planar heating element for preventing electromagnetic waves configured in a form of multiple layers of films to generate heat, the film type planar heating element comprising: a base film made of synthetic resin materials and formed in a sheet film shaped to be mounted on a floor; carbon heating units made of carbon materials and arranged in multiple rows to generate heat planarly on a top side of the base film when the planar element member is mounted on the floor; a pair of center-adjacent copper foil busbars disposed in a center area of the base film, applying current to the carbon heating unit, and facing each other in a close distance so that intensities of electromagnetic waves and magnetic field are mutually canceled each other when the current is applied; a pair of center silver busbars formed between the carbon heating unit and the center-adjacent copper foil busbars and made of silver materials allowing the current, which is applied to the center-adjacent copper foil busbars, to smoothly flow to the carbon heating unit, and a laminex film coated on the top side of the base film to protect the carbon heating unit and the center-adjacent copper foil busbars, characterised in that each the carbon heating unit comprises: a pair of busbar-carbon adhesion portions which is formed by cutting a center of the carbon heating unit and to which the pair of center-adjacent copper foil busbar is adhered, an adhesion connection portion extending to both sides of the busbar-carbon adhesion portions, and a pair of upper connection portions extending upward at outer ends of the adhesion connection portions when the planar heating element is arranged vertically, wherein two of the carbon heating units are interconnected through the upper connection portions such as to configure a dual carbon heating unit. a base film made of synthetic resin materials and formed in a sheet film shaped to be mounted on a floor; carbon heating units made of carbon materials and arranged in multiple rows to generate heat planarly on a top side of the base film when the planar element member is mounted on the floor; a pair of center-adjacent copper foil busbars disposed in a center area of the base film, applying current to the carbon heating unit, and facing each other in a close distance so that intensities of electromagnetic waves and magnetic field are mutually canceled each other when the current is applied; a pair of center silver busbars formed between the carbon heating unit and the center-adjacent copper foil busbars and made of silver materials allowing the current, which is applied to the center-adjacent copper foil busbars, to smoothly flow to the carbon heating unit, and a laminex film coated on the top side of the base film to protect the carbon heating unit and the center-adjacent copper foil busbars, characterised in that each the carbon heating unit comprises: a pair of busbar-carbon adhesion portions which is formed by cutting a center of the carbon heating unit and to which the pair of center-adjacent copper foil busbar is adhered, an adhesion connection portion extending to both sides of the busbar-carbon adhesion portions, and a pair of upper connection portions extending upward at outer ends of the adhesion connection portions when the planar heating element is arranged vertically, wherein two of the carbon heating units are interconnected through the upper connection portions such as to configure a dual carbon heating unit. a pair of busbar-carbon adhesion portions which is formed by cutting a center of the carbon heating unit and to which the pair of center-adjacent copper foil busbar is adhered, an adhesion connection portion extending to both sides of the busbar-carbon adhesion portions, and a pair of upper connection portions extending upward at outer ends of the adhesion connection portions when the planar heating element is arranged vertically, wherein two of the carbon heating units are interconnected through the upper connection portions such as to configure a dual carbon heating unit.
