Abstract
Provided are: an electrode for a gas sensor formed as a porous electrode so as to stably allow reduction in electrode resistance for excellent low-temperature activity; and a gas sensor. The electrode () for the gas sensor is adapted for use on a surface of a solid electrolyte body (), which is predominantly formed of zirconia, and contains particles () of a noble metal or an alloy thereof, first ceramic particles () of stabilized zirconia or partially stabilized zirconia and second ceramic particles () of one or more selected from the group consisting of AlO, MgO, LaO, spinel, zircon, mullite and cordierite, wherein the second ceramic particles are contained in an amount smaller than that of the first ceramic particles.
