A method of manufacturing a honeycomb structure. (1) Water is added to
silicon carbide particles and kneaded into a kneaded raw material. The
silicon carbide particles have an average particle diameter of not less
than 2 .mu.m and not more than the honeycomb rib thickness.times.0.23 and
a logarithmic standard deviation of the particle size distribution of not
less than 0.15 and not more than 0.40 (step S11). (2) The kneaded raw
material is extruded by extrusion into a honeycomb extruded body (step
S12). (3) The extruded body is dried (step S13), calcined (step S14), and
fired (step S15).
