PROBLEM TO BE SOLVED: To provide a detector having a structure making a protective tube hard to damage in a lead wire lead-out part and capable of arranging the protective tube at a right angle in low cost. SOLUTION: A detection part 3 and a heater 4 are housed in an almost cylindrical main body case 2 and the first and second lead wires 71, 72 electrically connected to the detection part 3 and the third lead wire 8 connected to the heater 4 are externally taken out of the opening part 22 of the main body case 2. A protective tube 6 is provided so as to cover the first, second and third lead wires 71, 72, 8. An elastomer 5 seals the opening part 22 and protrudes to the outside by predetermined length from the opening part 22. The through-holes 51, 52, 53 of the first, second and third lead wires 71, 72, 8 are provided to the central part of the elastomer 5. A recessed part 54 is formed to the leading end of the rear end of the elastomer 5 and one end of the protective tube 6 is positioned within the recessed part 54 so as to protrude from the opening part 22. |
