The particulates detector detects a particulate concentration at a predetermined sensed position. The particulates detector includes: an optical particulate sensor (321) that outputs a sensor output value (Vs) depending on the particulate concentration at the sensed position; and a correction section (322) that determines a corrected value (Vc) by correcting the sensor output value as a value indicating the particulate concentration. In a case where the sensor output value is fixed, the correction section performs the determination of the corrected value, such that the particulate concentration indicated by the corrected value decreases with decrease in wind speed at the sensed position.
