Abstract
A nitrous oxide concentration detector includes a control unit. In the control unit, a first control section controls a voltage application section and a heater to achieve a first state in which nitric oxide undergoes electrolysis and nitrous oxide does not undergo electrolysis. A second control section controls the voltage application section and the heater to achieve a second state in which nitric oxide and nitrous oxide undergo electrolysis. An estimation section estimates an estimated current that flows between a first electrode and a second electrode due to electrolysis of nitric oxide in the second state based on a first current detected by a current detector in the first state. A calculation section calculates a nitrous oxide concentration based on a third current obtained by subtracting the estimated current estimated by the estimation section from a second current detected by the current detector in the second state.
