Beschreibung
Zusammenfassung:	A PM detection device for an internal combustion engine includes a PM sensor outputting a signal in response to a resistance between a plurality of electrodes provided to a detection portion to which a particulate matter emitted from an internal combustion engine are attached, and a PM detection portion computing a PM attachment amount, which is an amount of a PM attached to the detection portion of the PM sensor, based on an output signal of the PM sensor by using a relation between the output signal of the PM sensor and the PM attachment amount. The PM detection portion corrects the PM attachment amount in response to an operating condition of the internal combustion engine when computing the PM attachment amount based on the output signal of the PM sensor.
