摘要:
A gas sensor has an elongated planar ceramic substrate carrying a gas-sensitive layer at one end thereof, and a ceramic layer overlaid on the substrate with a setback from the gas-sensitive layer so as to form a staircase-like step on the substrate, the setback edge surface of the ceramic layer being non-linear in the width direction of the substrate but preferably perpendicular to the plane of substrate.
