<p>There are disclosed a ceramic porous membrane formed with less membrane formation times and having less defects, a small and uniform thickness and a high resolution, and a ceramic filter. A silica membrane (1) as a ceramic porous membrane is formed on a titania UF membrane (14) as an ultrafiltration membrane (a UF membrane) formed on a porous base member (11) which is a microfiltration membrane (also referred to as an MF membrane) and having an average pore diameter smaller than that of the porous base member (11), the silica membrane has an average pore diameter smaller than that of the titania UF membrane (14) and a part of the silica membrane permeates the titania UF membrane.</p> |
