A method that can be used for on-vehicle diagnosis of fine particles is provided. A honeycomb structure having a large number of through-holes penetrating in the axial direction partitioned by partition walls, and having three or more electrodes arranged on the side surfaces at equal distances from one end face and separated from each other In the body, any two electrodes are selected from the electrodes, the electrical characteristics between the selected two electrodes are measured, and the arbitrary structures in the honeycomb structure are measured based on the measured electrical characteristics. This is a method for measuring the amount of particulates deposited in a honeycomb structure, which determines the amount of particulates deposited in the zone between the two electrodes.
