There are disclosed a method and a device for sealing an end portion of a porous structure having a columnar outer shape, such as a ceramic honeycomb filter, with a sealing material, so that the whole end portion can be uniformly coated with the sealing material, and a porous structure sealed at an end portion in a superior state by the method. In the method, an end portion of a porous structure 9 is sealed at an end face of the porous structure 9 having a columnar outer shape. A porous elastic material 13 having a predetermined thickness adhered on a planar base plate 15 is impregnated with a slurried sealing material, the porous elastic material 13 is pressed onto the end face of the porous structure 9 to coat the end portion of the porous structure 9 with the sealing material.
