PURPOSE: A catalyzed particulate filter is provided to effectively prevent damages to a partition wall by easily penetrating wash coat into a micro pore formed on the partition wall surface, and to prevent damages of the catalyzed particulate filter. CONSTITUTION: A catalyzed particulate filter(100) includes the following: a partition wall(105) forming a plurality of channels on which exhaust gas passes through; a plug alternatively opening and closing an inlet and an outlet of the channels; and a coating layer coated to an inner side of the channel. The coating layer includes a protect coating layer and a catalyst coating layer including metal components reacted with particulate materials included in the exhaust gas. |
