Abstract
A method of producing a mask to be used for the production of a ceramic filter is disclosed, wherein an ultraviolet ray-transmitting film, which cannot transmit ultraviolet ray at the portion corresponding to the through holes of a porous ceramic honeycomb structural body, into which holes a sealing material is to be injected at the opening end surface of the body, and can transmit ultraviolet ray at the portion corresponding to the through holes of the body, into which holes the sealing material is not to be injected at the opening end surface of the body, is made; the film is arranged on an ultraviolet ray-curable resin; ultraviolet ray is irradiated to the resin through the film; and the ultraviolet ray-uncured resin portion is removed from the resin. The mask matches to the porous honeycomb structural body, and a ceramic filter can be easily produced from the body.
