There is disclosed a plugged honeycomb structure manufacturing method capable of easily manufacturing a plugged honeycomb structure for use in a filter or the like at low costs so that deposits disposed on an end surface of the structure are reduced, a uniform plugging depth is achieved and especially the plugging depth of a slurry-like plugging material at an outer peripheral portion of the honeycomb structure is easily made uniform. In the method of manufacturing the plugged honeycomb structure in which the plugging portion is formed in one opening end portion of each of predetermined cells of a cylindrical honeycomb structure including a plurality of cells divided by porous partition walls to form channels of a fluid in the form of a honeycomb, a flexible porous member 2 impregnated beforehand with a slurry-like plugging material 1 is pressed onto an end surface 4a of a honeycomb structure 4 to thereby fill cell passages of the honeycomb structure 4 with the slurry-like plugging material 1 contained in the flexible porous member 2 and form plugging portions 4b.
