Abstract: In a method of detecting defects generated in a honeycomb structural body, both end sections of the honeycomb structural body is sealed along a flowing direction of exhaust gas. Air is supplied in the flowing direction of the exhaust gas from one end section to the other end section of the honeycomb structural body. Microphones are arranged at outer periphery of the honeycomb structural body and detect sounds of air leaking from a skin layer of the honeycomb structural body. A judgment step judges whether or not defects such as holes having not less than a predetermined diameter and cracks are generated on the basis of a magnitude of the detected sounds of the leaking air.
