Abstract
An electrochemical element for detecting a component in a gaseous fluid in an external space, including a planar solid electrolyte body, and a first and a second electrode which are disposed in contact with the planar solid electrolyte body and cooperate with the planar solid electrolyte body to form an electrochemical cell. The electrochemical element has a thin flat space which communicates with the external space and which has a predetermined diffusion resistance to the molecules of the component. A thickness of the thin flat space as measured perpendicularly to a plane of the planar solid electrolyte body is larger at an inlet portion thereof at which the thin flat space communicates with the external space, than at a remote portion thereof remote from the inlet portion. The first electrode is located at the remote portion.
