Claims

[Scope of utility model registration request]

In an oxygen sensor having a sensor element, a louver disposed to surround the sensor element, and a metal holder holding one end of the louver, the oxygen sensor includes a heat insulator that prevents heat conduction from at least the louver to the metal holder. An oxygen sensor characterized by having a means.
