Description of the Related Art Conventionally, a flat, tubular or cylindrical ceramic heater having a heating resistor embedded in a ceramic body has been widely used in various fields. However, an object to be heated such as a liquid or a gas heated by the ceramic heater is generally controlled so as to be maintained within a predetermined temperature range. That is, when the temperature reaches the lower limit of the predetermined temperature range, the heater is energized, the object to be heated is heated by the heat generated by the heater, and when the temperature reaches the upper limit temperature, the energization to the heater is stopped and the operation of stopping the heating is automatically performed. An automatic temperature control device that is repeated is widely used. Such a device requires a temperature sensor that accurately detects the temperature of the object to be heated without time delay, but a temperature sensor such as a thermostat or thermistor that has been conventionally used must be integrated with a heater. Could not be installed, it must be installed separately, depending on its position, the temperature distribution of the object to be heated may be uneven, or it may be in an oxidizing atmosphere, in an acid-alkaline solution, in a corrosive gas, etc. There were considerable restrictions on use in special environments.

If the gap is less than 0.2 mm, there is a possibility that a problem may occur in the insulation between the heating resistor 1 and the temperature-sensitive resistor 3. Is likely to be insufficient.

It is not necessary to separately install a temperature sensor, and it is possible to control the heating to an accurate and uniform temperature distribution without causing uneven heating in the temperature distribution of the object to be heated due to the location of the temperature sensor. Since the resistor is surrounded by a high thermal conductivity, electrical insulation, and a heat-resistant material, it has excellent responsiveness with temperature changes, and has extremely stable electrical insulation at high temperatures. Since the resistor is surrounded by physically and chemically stable ceramics, the heating resistor does not oxidize due to contact with air and is used as a heater or a temperature sensor in a special environment such as in a corrosive liquid. It is also possible to do. The temperature of the heating resistor, not the object to be heated, is measured by a resistance value corresponding to the temperature of the temperature-sensitive resistor, and extremely sensitive temperature control is possible.
