Abstract:
Provided is a planar heater for car including a stacked structure of a carbon nanotube heating layer which includes a far-infrared rays emitting layer, a metal layer, and a metal wire. The planar heater for car can increase the indoor temperature of an electric vehicle having no additional heating systems. Further, depending on where the planar heater for car is applied, the indoor temperature of a car that occupants feel comfortable can be maintained.
