Abstract
There is disclosed a manufacturing method of a plugged honeycomb structure so that the plugged honeycomb structure for use in a filter or the like having reduced deposits deposited on an end surface of the structure can easily be manufactured with low cost and so that a plugging depth of a slurry-like plugging member at an outer peripheral portion of the honeycomb structure can easily be set to be uniform. In the manufacturing method of the plugged honeycomb structure in which plugging portions are formed at opening end portions of predetermined cells on one side of a cylindrical honeycomb structure including a plurality of cells separated from one another by porous partition walls, constituting channels of a fluid and formed in a honeycomb-like shape, plugging members which are formed into a predetermined shape and which are to be inserted into cell passages to be plugged include a plastic material having viscosity and fluidity.
