Abstract
A particulate detection apparatus () controls a particulate sensor () for detecting the amount of particulates contained in exhaust gas and which has a pump () for supplying air to a detection section of the particulate sensor () into which the exhaust gas is introduced. The particulate detection apparatus () detects the flow rate of air supplied from the pump () to the particulate sensor () by a flow rate sensor (). The particulate detection apparatus () maintains a consistent detection accuracy of the particulate sensor () based on the result of the detection by the flow rate sensor ().
