Claims

[Scope of utility model registration request]

Two elements with porous electrodes formed on both sides of a plate-shaped solid electrolyte were fixed in parallel with a small gap open on three sides, and one element was used as an oxygen pump element and the other element as an oxygen concentration battery element. The protective tube that surrounds and houses the electrode part of the element placed in the measurement atmosphere of the sensor is a double tube with a gap through which the measurement atmosphere gas flows, and the outer tube has a line segment cut on the tube wall. Either one side of the cut point is recessed inward to form a recess that slopes in the circumferential direction, or
Alternatively, by bending the deflection piece in the circumferential direction so as to form a structure, a large number of gas introduction holes opening in the circumferential direction are formed, and the opening direction is oriented in one direction in the circumferential direction. A plurality of gas introduction holes are arranged in the same row, and one or more rows are arranged in corresponding positions of the electrode part in the axial direction, and the inner tube has a plurality of gas introduction holes formed in the circumferential direction. An oxygen sensor characterized in that a plurality of rows of dowels are arranged at positions corresponding to the electrode portions.
