ABSTRACT:
An exhaust gas purifying apparatus includes a metal casing and a honeycomb filter installed in the metal casing. The honeycomb filter includes cells, a first end face, and a second end face. The cells include a first cell and a second cell provided alternately. The first cell includes an open end on the first end face side and a sealed end on the second end face side. The second cell includes an open end on the second end face side and a sealed end on the first end face side. A cross-sectional area of the first cell is smaller than a cross-sectional area of the second cell. The first end face is disposed on a gas inlet side of the metal casing. The second end face is disposed on a gas outlet side of the metal casing.
