text: The second aspect of the present invention provides a process for producing a honeycomb structure constituted by porous cell walls which form a cell group consisting of a plurality of cells adjacent to each other, and a honeycomb outer wall which surrounds and holds the outermost peripheral cells located at a circumference of the cell group, in which honeycomb structure a porosity is 5% to less than 30%, a basic wall thickness (Tc) of the cell walls is 0.030
text: The characteristics of the present invention lie in satisfying all of the following three requirements; that is, the porosity of the total of the cell walls 2 and the outer wall 4 both constituting the honeycomb structure 1 is 5% to less than 30%, the thickness (T c ) of the cell walls 3 is 0.030 mm≦T c <0.076 mm and the average surface roughness (Ra s ) of the outer wall 4 is 0.5
