Abstract

多数のセルがセル壁を隔てて長手方向に並設され、セルのいずれか一方の端部が封止された柱状のハニカム焼成体からなり、一方の端面側から流入したガスが他方の端面側から流出するハニカムフィルタであって、ハニカムフィルタのガスが流入する側が開口したセルの長手方向に垂直な断面の総和が、ハニカムフィルタのガスが流出する側が開口したセルの長手方向に垂直な断面の面積の総和の１．５～３．０倍であり、ハニカムフィルタには、そのガス流出側端面からハニカムフィルタの全長の１０％の領域には触媒担持層が形成されておらず、ハニカムフィルタのガス流入側端面からハニカムフィルタの全長の９０％の領域のうち、ハニカムフィルタの全長の２５％～９０％の領域には触媒担持層が形成され、ハニカムフィルタの触媒担持層が形成されていない領域の熱伝導率は、ハニカムフィルタの触媒担持層が形成された領域の熱伝導率に比べて高い。
