Abstract
An ammonia gas sensor which includes a solid electrolyte member (310) extending in an axial direction; a reference electrode (320) provided on the solid electrolyte member (310); and a detection electrode (331) and a selective reaction layer (340) provided on the solid electrolyte member (310). The detection electrode serves as a counterpart of the reference electrode (320). The detection electrode (331) contains a noble metal as a predominant component, and the selective reaction layer (340) contains a metal oxide as a predominant component.
