Honeycomb filter for exhaust gas decontamination

A balsaming of the present invention claims a high external size precision, and capable of reducing the working manufacture procedure to the tail gas purifying of breakage uses the honey-comb filter. The exhaust gas to from the honey-comb filter structure, is composite provided with along the length direction with multiple through holes for porous ceramics part of the separating wall of the through the connecting piece layer is cakes in series, wherein insulating through hole wall of the display particle trapping function of filter, wherein, the connecting piece is set between the calorific parallel to the porous ceramic member set between the calorific capacitor is lower than.
