Abstract
A method for manufacturing a plugged honeycomb structure includes the steps of: applying a predetermined amount of the plugging slurry on a face of an end face sealing member, one end face of the masked honeycomb structure is pressed against the face to which the plugging slurry was applied of the end face sealing member to fill the plugging slurry in the predetermined cells on the one end face side, and drying at least the plugging slurry at a portion in contact with the face of the end face sealing member in a state that the face of the end face sealing member is pressed against the one end face of the masked honeycomb structure. The method can manufacture simply at a low cost a plugged honeycomb structure with reduced accumulation of deposit on an end face when the honeycomb structure is used as a filter or the like.
