<P>PROBLEM TO BE SOLVED: To provide a method for inspecting the strength of a honeycomb structure capable of simply and properly inspecting whether the honeycomb structure satisfies guaranteed strength, and a device for inspecting the strength of the honeycomb structure. Ž<P>SOLUTION: The method for inspecting the strength of the honeycomb structure having a large number of cells surrounded by a large number of cell walls arranged so as to form a cell shape of which the cross section vertical to a flow channel direction is polygonal and the cylindrical skin layer covering the outer peripheral side surface of the honeycomb structure has the pressure loading step for loading the outer surface of the skin layer of the honeycomb structure with inspection pressure through a pressurized fluid and the determining step for confirming the state of the honeycomb structure and determining whether the honeycomb structure satisfies the guaranteed strength capable of withstanding guaranteed pressure P0. In the pressure loading step, the honeycomb structure is applied with the inspection pressure so that the peak (s) of the inspection pressure distribution X in the axial direction on the outer surface of the skin layer of the honeycomb structure becomes two or more and the inspection pressure in the valley t2 between the peaks (s) becomes the guaranteed pressure P0 or higher.
