A laminated gas sensor includes a solid electrolyte layer, a measurement gas chamber, a reference gas chamber, a measurement gas chamber formation layer, and a reference gas chamber formation layer. The measurement gas chamber formation layer has an opposite pair of inner side surfaces that extend in a longitudinal direction of the solid electrolyte layer and face each other in a lateral direction of the solid electrolyte layer through the measurement gas chamber. The reference gas chamber formation layer has an opposite pair of inner side surfaces that extend in the longitudinal direction and face each other in the lateral direction through the reference gas chamber. Further, at least one of the inner side surfaces of the measurement gas chamber formation layer is located more inside the laminated gas sensor than a corresponding one of the inner side surfaces of the reference gas chamber formation layer in the lateral direction.
