Claims

[Scope of Claim for Utility Model Registration] (1) In a limiting current type oxygen sensor that is made of an oxygen ion conductor and has a detection part and a heater part, the oxygen sensor is provided in a space connected to a small hole that limits the amount of oxygen diffusion. An oxygen sensor comprising: a heat transfer section that transfers heat from the heater section to the detection section. (2) Utility Model Registration The oxygen sensor according to claim 1, wherein the heat transfer part is an oxygen ion conductor made of the same material as the other parts.
