Claims

[Scope of utility model registration request]

An oxygen sensor comprising a cylindrical oxygen sensing element with electrode layers on the inner and outer surfaces and one end closed, and an output lead wire electrically connected to the internal electrode layer on the inner surface of the oxygen sensing element. An oxygen sensor characterized in that a metal terminal that presses the inner periphery of the electrode layer in the radial direction from the inside is used at the connection portion between the output lead wire and the internal electrode layer.
