Abstract
A gas component detecting plug including a gas component-sensitive element, lead wires connected to the gas component-sensitive element, a tubular or board-like insulator which supports both the gas component-sensitive element and the lead wires, and an enclosure, the insulator being sealed to the enclosure so that the gas component-sensitive element is positioned on a leg portion side, characterized in that a spacer is disposed and retained in a gap formed between the insulator and the enclosure, in that a space on a head portion side formed by the insulator, enclosure, spacer and electrode wires is filled with glass and in that a rubbery elastic member having an insulating property is inserted in the head portion side. The gas component detecting plug is superior in water-proofness, gas-tightness, heat insulating property and productivity.
