Abstract
The invention relates to a solid electrolyte comprised of partially stabilized zirconia, and a gas sensor including the solid electrolyte. The partially stabilized zirconia includes crystal particles, the crystal particles include at least stabilizer low-concentration phase particles, and the partially stabilized zirconia further includes voids. Among the stabilizer low-concentration phase particles, the presence rate of the stabilizer low-concentration phase particles where each distance from a void is 5 μm or less is 65 volume percent or more. The stabilizer low-concentration phase particles include specific stabilizer low-concentration phase particles each having a distance of 5 μm or less from an adjacent void in the voids, a presence rate of the specific stabilizer low-concentration phase particles having 65 volume percent or more.
