Abstract
An odor measurement device includes a sensor having an adsorption film that adsorbs an odorant and outputting a signal corresponding to adsorption of the odorant, a first pump that supplies a first gas containing an odorant to a housing chamber that houses the sensor, a second pump that supplies a second gas for desorbing the odorant from the adsorption film to the housing chamber, and a control device including a determination unit that measures the odorant based on information on an output signal of the sensor in a desorption process in which the odorant is desorbed from the adsorption film, and a control unit that sequentially executes a first mode in which the first gas is supplied to the housing chamber and a second mode in which the second gas is supplied to the housing chamber and the odorant is measured by the determination unit.
