摘要：A particulate matter measuring device includes: a diesel particulate filter (DPF)in which upstream side and downstream side openings of multiple cells partitioned by

porous partition walls are alternately plugged; a pair of first electrodes received in a pairof first electrode cells arranged diagonally with a central cell therebetween; a pair ofsecond electrodes received in a pair of second electrode cells arranged diagonally withthe central cell therebetween; a first connecting member for connecting the firstelectrodes to each other; a second connecting member for connecting the secondelectrodes to each other; and a unit that calculates an amount of particulate mattertrapped in the DPF on the basis of capacitance between the electrodes. The four cellswhich are adjacent to each other around the partition walls of the central cell andsandwiched between the first electrode cells and the second electrode cells are used asmeasurement cells.
