Abstract
To present a ceramic sheet with catalyst high in porosity, excellent in combustion efficiency, and easy to process into any desired shape, an inorganic oxide 4 carrying a noble metal catalyst 5 is dispersed and mixed together with ceramic fibers 1 and an inorganic binder 2, and an inorganic flocculant and an organic binder 3 possessing the flocculating effect are added to form flocs, a sheet is formed by a paper making method, and it is heated at 950.degree. C. or less, thereby obtaining a ceramic sheet carrying the noble metal catalyst in a state of being uniformly dispersed in the entire inner parts.
