To provide a method of producing a honeycomb structure which develops substantially no sealing defects even when it is ground after through-cells are sealed, and to provide an end face-treated honeycomb structure having substantially no sealing defects and a solid-liquid separation filter.
A method of producing a honeycomb structure 3A comprises: a step of preparing a honeycomb structure raw body 7; a first filling step of filling a first sealing material 21 from one open end parts to other open end parts of through-cells 11b of the honeycomb structure; a first curing step of curing the first sealing material 21; a second filling step of filling a second sealing material 22 to gaps 24 defined in the first sealing material 21; and a second curing step of curing the second sealing material 22. The honeycomb structure 3A has ground surfaces on its end surfaces and exposed surfaces of a sealing member 13 and a solid-liquid separation filter includes the honeycomb structure 3A and separation filters 4.
