    摘要: Provided is an exhaust gas purifying filter which shortens the combustion time of the particulate matter that is deposited on the partition walls, during the regeneration of a ceramic honeycomb structure, while maintaining the efficiency of capturing the particulate matter and suppressing an increase in the pressure loss, thereby preventing the destruction of the ceramic honeycomb structure, and which can also reduce the fuel use that is required to increase the exhaust gas temperature and bring about an enhancement of the fuel efficiency. The exhaust gas purifying filter of the present invention includes a filter body (11) formed from a porous body having an inflow surface through which an exhaust gas containing particulate matter flows in, an emitting surface through which purified gas is emitted, and a number of fine pores, and the filter body (11) has a partition wall (14) and a number of gas flow channels (12) surrounded by the partition wall (14) and extended along the longitudinal direction thereof, and a porous membrane (13) containing at least silicon and carbon is provided on the inner wall surface (12a) of the gas flow channel (12).
