Claims

[Scope of utility model registration request]

(1) A flat part of a cylindrical solid electrolyte oxygen sensor element with electrode layers provided on both sides of the solid electrolyte is provided opposite to a flat part of the stem, and two oxygen sensor elements are attached to this oxygen sensor element with an isolated space between them. 1. An oxygen sensor, characterized in that a metal member having a large number of through-holes is covered with a cover made of a dust-proof energizing member filled between the metal members.
(2) The oxygen sensor according to claim 1 of the utility model registration, characterized in that a louver is provided around the cover.
