| I.P Abstract & Summary |
The present invention relates to a film type planar heating element minimizing electromagnetic waves, and more specifically, to a film type planar heating element that can be used safely without concerns regarding electromagnetic waves by arranging center-adjacent copper foil busbars, which apply current to a carbon heating unit in a center area of a base film to generate heat, to face each other in a close distance in the center of the base film; can conveniently generate heat a large area; can significantly improve heating efficiency by allowing the current to be applied from the center to both sides of the carbon heating portion to generate heat; and can prevent sparks generated when the current is applied to ensure safe operation. |
