PROBLEM TO BE SOLVED: To provide a grinding method of a honeycomb structure for forming a honeycomb structure which has a ring-shaped protrusion part, which is formed in a tapered shape, on an outer circumference in a short time by improving a profile of a processed surface.SOLUTION: In a grinding method of a honeycomb structure 41, a grinding member 1 having an outer circumference surface 4, a first grinder tapered surface 5, and a second grinder tapered surface 6, grinds a honeycomb segment joined body 11 rotating around a center axis while rotating the grinding member around the center axis. A first ground region 21, a second ground region 23, a center ground surface 33, a first tapered surface 31, and a second tapered surface 32 are formed by the respective surfaces of the grinding member 1 to produce the honeycomb structure 41 having a cylindrical honeycomb base material 42, and a ring-shaped protrusion part 43 which surrounds the outer periphery of the honeycomb base material 42, protrudes in a flange shape from an outer circumference of the honeycomb base material 42 to an outer side, and includes the first tapered surface 31, the second tapered surface 32, and the center ground surface 33. |
