Abstract (en)

A heater tube (3) comprises a smaller-diameter portion (31) and a larger-diameter portion (32). A first resistor (4) and a second resistor (5) are provided in the heater tube (3). The second resistor (5) has a positive resistance-temperature coefficient larger than that of the first resistor (4). The first resistor (4) and the second resistor (5) are electrically connected in series. The entire body of the first resistor (4) and 3/4 of the second resistor (5) are accommodated in the smaller-diameter portion (31). <IMAGE>
