<p>A catalyst holding filter reducing a pressure loss. A catalyst holding filter (10)is made of a ceramic support (4) of SiC covered with a catalyst layer (2). An average pore size of the ceramic support is 10-250 mu m, and a porosity of the ceramic support is 40-80%. The catalyst layer contains a catalyst, a cocatalyst and a support material. <IMAGE></p> |
