Abstract
The sensor includes: a collection partL,M,S in which a plurality of filter members for collecting particulate matter in exhaust gas are arranged in descending order of porosity from an exhaust upstream side to an exhaust downstream side of the exhaust gas; a pair of electrodeswhich is arranged to each of the plurality of filter membersL,M,S and facing each other with the plurality of filter members interposed therebetween; and estimation meanstofor estimating a particulate matter amount collected on each of the plurality of filter members having different porosities based on a capacitance change amount between the pair of electrodes
