An object of the present invention is to provide a ceramic heater so that the uniformity of temperature on its heating face may be improved and cold spots on the heating face may be effectively prevented. The ceramic heater 1 has a ceramic substrate 2 having a heating face 2a, a heating resistance embedded in the substrate 2 and a terminal 6 electrically connected with the resistor. The resistor includes first windings 3A, 3B and second winding 4. The first winding 3A or 3B has a winding diameter larger than that of the second winding 4. A non-wound wire may be used instead of the second winding 4.
