For example, the conductive heating thin film 110 may be formed of a carbon-based material including carbon nanotubes. Such carbon-based materials including carbon nanotubes include single wall carbon nanotubes (SWCNTs) or multiwall carbon nanotubes.

The electrode unit 120 functions to flow a current to the conductive heat generating thin film 110. The electrode unit 120 may be formed of a metal having transparency such as Ag nanowire / paste, indium tin oxide (ITO), zinc oxide (ZnO) , SnO 2 (tin oxide) or a non-oxide transparent electrode such as carbon nanotube or graphene, but the present invention is not limited thereto. However, for convenience of explanation, the case where the electrode part 120 is formed of silver (Ag) nanowire will be mainly described below.

The electrode unit 120 may be formed using a solution process such as spin coating, dip coating, inkjet printing, offset printing, reverse offset printing, gravure printing, or roll printing on the top surface of the conductive heating thin film 110. At this time, the electrode unit 120 may be formed on the upper surface of the conductive heating foil 110, or may be formed on the upper surface of the conductive heating foil 110 by etching the space where the electrode unit 120 is to be installed, It is also possible to arrange it.

The thickness of the electrode unit 120 is not limited, and for example, may be formed to have a thickness of approximately 100 μm.

Figure 5 shows the case formed.

In this case, the first branch electrodes 122 are formed to be vertically symmetrical with each other, but are not limited thereto. However, an end of the first branch electrode 122 branched from the first main electrode 121 installed on the upper portion of the conductive heating thin film 110 and branched from the first main electrode 121 provided on the lower portion of the conductive heating thin film 110. Ends of the first branch electrodes 122 may not be in contact with each other, and may be formed to be spaced apart from the center of the upper surface of the conductive heating thin film 110 by a predetermined interval.

In this case, the second branch electrodes 124 are formed to be vertically symmetrical with each other, but are not limited thereto.

The second branch electrodes 124 may be disposed not to overlap with the first branch electrodes 122, and the first branch electrodes 122 and the second branch electrodes 124 may be alternately disposed. For example, as shown in FIG. 1, upper portions of the first branch electrodes 122 and the second main electrode 123 branched from the first main electrode 121 formed on the conductive heating thin film 110. The second branch electrodes 124 branched in the direction are alternately disposed, and the second branch electrodes 122 and the second main branch branched from the first main electrode 121 formed at the lower end of the conductive heating thin film 110. The second branch electrodes 124 branched in the downward direction of the electrode 123 may be alternately disposed.
