1. A heater integrated gas chromatography (GC) column device comprising:
a bobbin formed of a metal having a high thermal conductivity;
an insulating layer including a metal oxide film formed on an inner surface of the bobbin;
a heat generating layer bonded to the insulating layer and including any one or more selected from the group consisting of carbon nanotubes and a carbon nanotube-metal composite;
a metal electrode formed to be in contact with the heat generating layer; and
a GC column wound around the bobbin while being adjacent to an outer surface of the bobbin.
