Claim 3:
4. The gas sensor according to claim 3,
wherein, when k is an integer from 1 to n−1, a ratio Rk+1/Rk between a k-th diffusion resistance Rk and a (k+1)-th diffusion resistance Rk+1 is greater than 1 and less than or equal to 100, the k-th diffusion resistance Rk being a diffusion resistance of a route of the measurement-object gas from an outside to a k-th measurement electrode, the (k+1)-th diffusion resistance Rk+1 being a diffusion resistance of a route of the measurement-object gas from the outside to a (k+1)-th measurement electrode.
