Abstract: A porous article is obtained by filling pores of at least one principal surface of a porous body which is formed of an inorganic material, with a mixture containing metal oxide particles and an alkaline silicate, in which the filled mixture is coated by a film containing a hydrated compound of zirconium and a silicate. According to this porous article, an effect of preventing surface contamination is superior, and alkali resistance and acid resistance are superior. In addition, a production treatment of the porous article can be performed at room temperature or at a relatively low temperature of 100° C. or lower. Therefore, the production cost can be significantly reduced.
