technical field

[0001] This application claims Korean Patent Application No. 10-2017-0168349 filed with the Korean Intellectual Property Office on December 8, 2017 and Korean Patent Application No. 10-2018 filed with the Korean Intellectual Property Office on November 22, 2018, respectively - Priority and benefit to 0145328, both patent applications are hereby incorporated by reference in their entirety.

[0002] The present application relates to a heating film and a manufacturing method thereof. Background technique

[0003] Moisture or frost appears on the car glass when there is a difference between the outside temperature of the car and the inside temperature. Heated glass can be used to solve this problem. Heated glass is used as a concept of attaching a hot wire sheet to the glass surface or forming a hot wire directly on the glass surface, and increasing the temperature of the glass surface by applying electric power to both ends of the hot wire to generate heat fr...
