ELECTRIC HEATING UNIT AND ELECTRIC CUSHION

摘要

PURPOSE: An electric heating unit and an electric cushion are provided to enhance the efficiency of energy under the low power by printing a conductive film and a heating film on a base film. CONSTITUTION: A conductive film(120) is formed in line on a base film(110). The conductive film is formed with a first material having a first resistance. A heating film(130) has the same shape as the conductive film. The heating film is formed on the conductive film. The heating film is formed with a second material having a second resistance. The heating film is heated when the power is applied to the conductive film. The cover film(140) is adhered on the base film in order to protect the conductive film and the heating film. A couple of connection terminals(150) are connected to both ends of the conductive film.
