ABSTRACT:
A honeycomb filter for exhaust gas purification, possessing a honeycomb structure (1) having a plurality of through-holes which are separated from each other by porous partition walls and plugged alternately at the exhaust gas inlet face (2) and the exhaust gas outlet face (3), wherein the honeycomb structure (1) has a slit (5) possessing an opening at least at the exhaust gas inlet face (2), and the slit (5) is partially filled with a filler (6) in a depth of 3 to 25 times the width (5d) of slit from the exhaust gas inlet face (3) toward a flow direction (10) of exhaust gas and a gap (5e) is formed inside from a portion of the slit filled with the filler (6). This honeycomb filter for exhaust gas purification has high purification ability, yet possesses high thermal shock resistance, and can be used continuously over a long period.
