Honeycomb structure and exhaust gas treating apparatus

An exhaust gas treating apparatus, comprising:

• a honeycomb structure having a longitudinal direction, comprising:
• a first end face;
• a second end face opposite to the first end face along the longitudinal direction;
• four honeycomb units each comprising:
• inorganic particles;
• an inorganic binder;
• and a plurality of cell walls extending from the first end face to the second end face to define a plurality of cells, the plurality of cell walls including a first cell walls extending
• along a first direction in a cross sectional plane perpendicular to the longitudinal direction and a second cell walls extending along a second direction substantially perpendicular to the first direction in the cross sectional plane;
• and adhesive layers provided between the four honeycomb units to connect the four honeycomb units each other, the adhesive layers extending in a first extending direction and a second extending direction substantially perpendicular to the first extending direction in the cross sectional plane, a minimum angle between the first direction and the first extending direction or the second extending direction is approximately 22.5 degrees to approximately 45 degrees;
• a metal casing containing the honeycomb structure;
• and a holding sealing member disposed between the honeycomb structure and the metal casing to hold the honeycomb structure at a predetermined position in the metal casing, wherein each of the honeycomb units has a fan shape in the cross sectional plane, wherein:
• each of the cells are through holes that are open at both an upstream end and a downstream end thereof and each of the four honeycombs units forming substantially a quarter of an overall cross sectional area of the honeycomb structure.
