Abstract
A method of producing a honeycomb structure of the present invention includes the steps of: forming plugged portions by dipping an end face of a honeycomb structure in slurry in a container, and pressing the honeycomb structure against an inner bottom surface of the container to force the slurry into at least some of the cells; and bringing out the honeycomb structure from the container to obtain the honeycomb structure having at least some of the cells being plugged. An air layer is formed between the plugged portions and the inner bottom surface of the container to separate them from each other in advance of bringing out the honeycomb structure having plugged portions from the container.
