<p>A nitrogen-oxide gas sensor that is able to measure a nitric oxide and a nitrogen dioxide at the same time, and ensure sensing accuracy and stability over a long period of time. The nitrogen-oxide gas sensor includes: a first oxygen ion conductive solid electrolyte; a first film contacting the first oxygen ion conductive solid electrolyte and formed of a metal oxide; a second film contacting the first oxygen ion conductive solid electrolyte and formed of a metal oxide; a power supply source for applying a current to the first and second films by electrically connecting a first node to the first film and a second node to the second film; a measurement unit for measuring an electric potential difference between the first and second nodes; and a temperature adjustment unit for uniformly maintaining a temperature of at least one of the first and second films.</p>
