[0035] The ceramic heater 100 includes a heater body 110 and a ceramic heating unit 120; wherein the ceramic heating unit 120 is used to generate heat and complete the heating work by transferring the heat to the medium in the heater body 110. In the process of the ceramic heating unit 120 transferring the heat to the medium in the heater body 110, since a metal sintered layer 121 is provided on one side of the ceramic heating unit 120, and the metal sintered layer 121 is connected to the heater body 110, through such a setting, the thermal resistance in the process of heat being transferred from the ceramic heating unit 120 to the medium in the heater body 110 can be reduced through the setting of the metal sintered layer 121, thereby improving the heat transfer efficiency, thereby improving the heating efficiency of the ceramic heater 100, and due to the high heat transfer efficiency, heat loss can be reduced, thereby also reducing heating energy consumption.

[0036] On the basis that a metal sintered layer 121 is provided on one side of the above-mentioned ceramic heating unit 120, when the ceramic heating unit 120 is connected to the heater body 110, a method of sintering alumina ceramics in surface contact with the heater body 110 can be adopted to improve the efficiency of heat transfer, and the heater body 110 adopts an aluminum structure, so that the heater body 110 can be connected to the side of the ceramic heating unit 120 provided with the metal sintered layer 121 by welding.
