<p>A method and a device for inspecting a honeycomb structure having porous partition walls (2) disposed so as to form a plurality of flow passages (3a) and (3b) passed through the honeycomb structure from one end face (42) to the other end face (44), the device comprising a water particle generating part (11) generating water particles (10), a water particle lead-in part (12) leading the water particles (10) into the plurality of flow passages (3a), and a discharged particle measuring part (13) measuring the particle size distribution and the quantity of particles of the water particles (10) discharged from the plurality of flow passages (3b). By the device and method, the honeycomb structure can be easily inspected for presence or absence of defects, sizes of defects, quantity of defects, and the sizes and quantity of pits, and a post-treatment can also be easily performed. <IMAGE></p> |
