ABSTRACT:
Using a slurry filler having a container having an opening top and storing plugging slurry and a cover attached to the opening top of the container and having a flat upper face and through-holes communicating the inside and the outside of the container and being disposed to correspond to cells to be plugged on an end face of the honeycomb structure, the honeycomb structure is set on the cover by positioning so that opening ends of cells to be plugged of the honeycomb structure match positions of through-holes of the cover, and the plugging slurry stored in the container is filled inside opening ends of cells to be plugged through the through-holes to form the plugged portions. According to this manufacturing method, a plugged honeycomb structure having no defects can be manufactured at low costs for a short time without restriction on operation circumstances with less industrial waste.
