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.
