The present invention relates to a heating apparatus having the structure of a nichrome strip. Particularly, the present invention relates to a heating apparatus having the structure of a nichrome strip with improved heating efficiency by controlling length and width while forming a heating line with a strip of a nichrome material. A heating device (10) includes a base substrate (12); and a nichrome strip (11) fixed to the base substrate (11). The nichrome strip (11) is connected from an input terminal (11a) to an output terminal (11b). It is extended from the input terminal (11a) to the output terminal (11b), with a screw line structure or a zigzag structure. The thickness of the nichrome strip (11) is determined by the frequency of applied power. |
