A heating film is provided to input a current into a plurality of carbon fibers by stably maintaining an electric connection state between the carbon fibers and copper thin plates by using a conductive wire. A heating film includes a plurality of carbon fibers(120), a first copper thin plate(130), and a conductive wire. The plurality of carbon fibers are formed between a first PET film(110) and a second PET film(112) at predetermined intervals. The first thin plate enables electrical connection so that power is inputted into both ends of each of the carbon fibers. An end portion of the carbon fiber is attached to an upper part of the first copper thin plate. At least one conductive wires are further disposed in the upper part of the first copper thin plate so that the first copper thin plate is in electric connection with the carbon fiber in a length direction of the first copper thin film. A second copper thin plate(132) is disposed in an upper part of the carbon fiber. One extension portion of the first copper thin plate is attached to a top surface of the second copper thin plate. |
