This invention provides a method of manufacturing a ceramic heater which includes the steps of: preparing a ceramic heater base member; applying a platinum paste to a surface of the heater base member so as to form a heater pattern on the surface; applying a ceramic paste to the surface of the heater base member so as to form an insulating layer that covers the heater pattern on the surface; and firing the heater base member with the heater pattern and the insulating layer formed thereon, wherein in the firing step, differences among maximum shrinkage percentages of the heater base member, the heater pattern, and the insulating layer are less than or equal to 5%. With the method, interfacial separation is prevented from occurring at the interfaces among the heater base member, heater pattern, and insulating layer, thus resulting in the ceramic heater having superior insulation properties and durability.
