Laminated gas sensor for motor vehicle, has measurement gas chamber formation layer with inner side surfaces located inside sensor corresponding to surfaces of reference gas chamber formation layer in lateral direction of electrolyte layer

摘要

The sensor (1) has a measurement gas chamber formation layer (13) with a hollow space laminated on a main surface of a solid electrolyte layer (11), so that the hollow space forms a measurement gas chamber (130). A reference gas chamber formation layer (12) has another hollow space laminated on another main surface of the electrolyte layer, so that the latter space forms a reference gas chamber (120). Inner side surfaces of the measurement layer are located inside the sensor corresponding to inner side surfaces of the reference layer in a lateral direction of the electrolyte layer.
