Abstract
The particulate matter detection sensor includes a conductive part, and the pair of electrodes that are arranged at specified spacing so as to face each other. The conductive part is formed into a plate shape using a conductive material having electrical resistivity that is higher than particulate matter. One major surface of the conductive part functions as an accumulation surface on which particulate matter accumulates. The pair of electrodes are formed on this accumulation surface.
Claims9
A particulate matter detection sensor for detecting an amount of particulate matter that is included in exhaust gases, comprising:
- a conductive part that is formed into a plate shape using a conductive material having electrical resistivity that is higher than the particulate matter, with one major surface functioning as an accumulation surface on which the particulate matter accumulates;
- and
- a pair of electrodes that are formed on the accumulation surface and arranged so as to be separated from each other and to face each other.
