Abstract
A particulate matter detection device includes a plate-like element base material including, on one surface thereof, a formed recess portion to collect a particulate matter; a pair of measurement electrodes arranged on the bottom surface side of the recess portion of the element base material; and a high-voltage dust collection electrode embedded in a wall which forms the recess portion of the element base material on the one surface side of the element base material from a position where the pair of measurement electrodes are arranged. An electric field is generated from the high-voltage dust collection electrode to the pair of measurement electrodes, to collect, on the bottom surface side of the recess portion, the particulate matter flowing along the element base material, and a change of electric characteristics between the pair of measurement electrodes is measured to detect the particulate matter collected on the recess portion.
