ABSTRACT:
A ceramic filter having a honeycomb structure10having a large number of cells which are extending in the longitudinal direction and which are alternatively plugged on an exhaust gas G inlet side end face10aand an exhaust gas G outlet side end face10bto form plugged portions. The depth of the inlet side plugged portions (filler16) is formed deeper than that of the outlet side plugged portions (filler16). Since the exhaust gas G tends to have a decreased turbulent flow and an increased laminar flow on the inlet side, a partial accumulation of Oil-Ash on portions near an outlet side end face can be inhibited.
