Abstract
To provide a particulate matter purifying device which is capable of providing excessive deposition of particulate matter. In the particulate matter purifying device, a catalyst elementis carried on a porous filter substratethrough which an exhaust gas passes. The particulate matter purifying device traps particulate matter contained in the exhaust gas, and oxidizing the trapped particulate matter to remove. This particulate matter purifying device is characterized in that active oxygen producing fine particlesare carried on a surface of the filter substratebetween the catalyst elements. Therefore, the particulate matter is partially damaged by the active oxygen produced by the active oxygen producing fine particles. Consequently, oxidization of the particulate matter is promoted so that deposition of the particulate matter is prevented or minimized.
