<p>A gas-sensing device (1) is cooled down from 1470 DEG C to 457 DEG C after calcination when manufactured. The device comprises a solid electrolyte plate (11) made of partially stabilized zirconia, a measurement electrode (121) disposed on the plate to face an atmosphere of a gas to be measured, and a reference electrode (131) disposed on the plate to face an atmosphere of a reference gas. A gas-permeable diffusion layer (141) is laminated on the plate to cover the measurement electrode. A gas-non-permeable shield layer (142) is laminated on the diffusion layer. A reference-gas-chamber forming plate (15) is laminated on the solid electrolyte plate to form a reference gas chamber. One or more of the shield layer, diffusion layer, and reference-gas-chamber forming plate are made of a material that differs in a contraction percentage from the solid electrolyte plate by an amount of 0.3 % or less. <IMAGE></p> |
