Abstract

A method of applying a circumferential coating material on a circumferential surface of a ceramic honeycomb structure to form a circumferential coat layer. The method includes vertically aligning the longitudinal axis of the ceramic honeycomb structure, rotating the ceramic honeycomb structure around the vertically-aligned longitudinal axis, and applying the circumferential coating material on the circumferential surface of the rotating honeycomb structure at a discharge speed of 50 to 120 mm/s, calculated byDischarge speed[mm/s]=Supplied amount[g/s] of circumferential coating material÷(Density ρ [g/mm] of circumferential coating material×Area[mm] of discharge opening).
