(EN)
The sensor comprises: traps 30L, 30M, 30S in which a plurality of filter members for trapping particulate substances in exhaust gases are arranged in order of higher porosity from the upstream end to the downstream end of the exhaust gases; electrodes 32, 33 arranged on the filter members 30L, 30M, 30S so as to face one another with the filter members 30L, 30M, 30S interposed therebetween; and estimation units 42-44 for respectively estimating, for each of the filter members, the particulate mass respectively trapped by the filter members 30L, 30M, 30S of different porosities, on the basis of the amount of change of electrostatic capacitance among the pairs of electrodes 32, 33.
