PURPOSE: A resistance heating composition is provided to manufacture a high-conductivity resistance heating body in a spray type in the low viscosity, and is provided to enable the molding and implementing the high conductivity. CONSTITUTION: When a resistance heating body is formed by using a silicone emulsion particle and a carbon nano-tube having different electric charge, the carbon nano-tube is able to be combined around the silicone emulsion particle by the static electrical power, thereby maximizing the volume effect and improving the conductivity. When the deformation of the resistance heating body is generated by the external stress condition, the breaking of the silicon material and the degradation of the electric conduction are able to be prevented.

The disclosed heating member comprises a resistance heat generating layer, a base material which supports the resistance heat generating layer, and an electrode which touches both sides of the longitudinal direction of the resistance heat generating layer and supplies a current to the resistance heat generating layer. The resistance heat generating layer comprises a notification region and a non-notification region on both sides of the notification region. A thermal conduction layer for preventing the overheating of the resistance heat generating layer is provided between the resistance heat generating layer and the base material in the notification region. The contact area of the thermal conduction layer and the resistance heat generating layer is 5-25% of the area of the non-notification region.
