ABSTRACT:
To provide an oxygen sensor having a heater unit without being broken by vibration impact of a vehicle, the oxygen sensor includes a cylindrical oxygen detecting element with a closed bottom and a heater unit installed in an inside of the oxygen detecting element. The heater unit includes insulators, the heat generating body helically wound a surface thereof and lead wires. In the insulators, concave portions reaching lead holes are disposed. Lead wires are put through the lead holes from an outer circumferential surface. In the concave portions, the heat generating body and the lead wires are connected. The outer circumference of a winding portion of the heat generating body is preferably formed at a position more inwardly than the outer circumferential surface of the adjacent insulator.
