Abstract: A method of manufacturing a honeycomb structure, the method including: a circumferential coat layer forming process of applying a circumferential coating material on a circumferential surface of a ceramic honeycomb structure to form a circumferential coat layer, the circumferential coat layer forming process including: a rotating process of matching an axial direction of the honeycomb structure; and an applying process of discharging the circumferential coating material to apply the circumferential coating material on the circumferential surface of the honeycomb structure that rotates, wherein in the applying process, a discharge speed of the circumferential coating material, calculated by Equation (1), discharged from the discharge nozzle is 50 to 120 mm/s, and Discharge speed V [mm/s]=Supplied amount q [g/s] of circumferential coating material÷(Density ρ [g/mm3] of circumferential coating material×Area S [mm2] of discharge opening)  (1).
