Relationship between the change of coke pore structures and asphalt pitch addition (ASP) was measured by image analyzing of coke cross section. Coke pore circularity was increased by addition of 10% ASP, which corresponded with the change of DI^<150>_<0.5-6>. When ASP was added excessively to blended coal, large pore increased, while average pore wall thickness increased. The large pore was observed around ASP high concentration part, rather than inside the part. It suggests the excess gas from ASP diffused to surroundings and there it combined.
