Zusammenfassung:	A nitrogen oxide concentration measurement device (10) comprises a zero scrubber (13) disposed within a gas flow path (16), and a controller (28). The zero scrubber (13) performs subjects exhaled air flowing through the gas flow path (16) from a mouthpiece (11) toward a chamber (15) to a NO removal treatment in a first period, out of a first period and a second period. The controller (28) acquires the concentration of NO contained in the exhaled air on the basis of the differential voltage value (Vd) outputted in the second period, which uses as a reference the differential voltage value (Vd) outputted in the first period.
