Therein, a heater guide portion 9 is formed of a terminal end face and a ringed groove 8 made circumferentially on the end portion to be contacted with said heaters 3 of said lead terminals 4, and a plural number of heater guide holes 10 are axially formed through said guide portion 9 correspondingly to each of said heaters 3. The medium portion of said heaters 3 is guided and held by said guide holes 10, and the lead-out end portion is connected to said lead terminals 4. Thereby, said guide portion 9 enabled to cope with the force working on said heater 3 so that the durability thereof is improved.
