Claim 1:
2. The method for producing the conductive honeycomb structure according to claim 1,
wherein, in the cross section perpendicular to the flow passage direction of the cells of the honeycomb fired body, the predetermined regions have a central region from a center to ½r of the cross section, and an outer peripheral region from ½r to r, in which r is a radius of the cross section, and
the step of controlling the volume fraction of the portion that can form the pores of the honeycomb formed body comprises controlling the absolute value of the difference in the volume fraction of the portion that can form the pores in each of the central region and the outer peripheral region of the honeycomb formed body relative to the previously set, predetermined porosity of each of the central region and the outer peripheral region of the honeycomb fired body to be within 0.5%.
