Abstract
A gas sensor for dealing with a measurement gas in an external space, having (a) an electrochemical pumping cell including a porous solid electrolyte body, and a first and a second electrode which are disposed on opposite sides of the porous solid electrolyte body, (b) a gas-tight ceramic body cooperating with a porous solid electrolyte body of the electrochemical pumping cell, to define therebetween an internal space, such that the first electrode substantially communicates with the internal space, and (c) a gas-tight solid electrolyte layer formed on or within the porous solid electrolyte body such that the first electrode is substantially entirely overlapped by the gas-tight solid electrolyte layer, as viewed in a direction perpendicular to a plane of the first electrode. The gas-tight solid electrolyte layer is formed to permit a portion of the porous solid electrolyte body to communicate with the internal space in the above-indicated direction.
