An electric roasting pan according to the present invention comprises: a roasting pan; a heating layer being in surface contact with the roasting pan and comprising a carbon nanotube and a silicone-based adhesive; and an electrode in contact with the heating layer. The electric roasting pan has excellent thermal efficiency thanks to the minimal heat loss thereof, can reach a target temperature within a short time to reduce a preheating time, and affords excellent cooking quality. Furthermore, the electric roasting pan can substantially prevent the occurrence of temperature deviation across the area of the roasting pan during a temperature increase and is of high durability and safety.
