Abstract

To provide a method for inspecting honeycomb structure that allows simply inspecting a deformation state of cells open to an end face of a honeycomb structure. The method for inspecting honeycomb structure sets a honeycomb structure as an inspection target. The method for inspecting honeycomb structure includes a process A. The process A measures a size of an inscribed circle 15 internally in contact with a partition wall 1. The partition wall 1 defines cells 2. The size of the inscribed circle 15 of at least the one cell 2 among these plurality of cells 2 open to a first end face of the honeycomb structure is measured. In the process A, when the cell 2 where the size of the inscribed circle 15 internally in contact with the partition wall 1 is to be measured is set as a measurement cell 2x and the cell 2 where the size of the inscribed circle 15 internally in contact with the partition wall 1 is not to be measured is set as the non-measurement cell 2y, at least the one cell 2 among the cells adjacent to the one measurement cell 2x is set as the non-measurement cell 2y and at least one cell among the cells 2 adjacent to the one non-measurement cell 2y is set as the measurement cell 2x.
