摘要：
The method for producing a porous honeycomb structural body according to the present invention is the method, which comprises preparing a green body by kneading a forming material containing a main constituent material consisting of non-oxide ceramics and/or a metal and an organic binder, manufacturing a honeycomb shaped formed body (honeycomb formed body) by shaping and drying said green body, calcining the honeycomb formed body to obtain a calcined body, and firing finally the calcined body to obtain a porous honeycomb structural body,wherein said forming material further includes 0.01-10 parts by mass of an inorganic layer material to 100 parts by mass of said main constituent material, in addition to said main constituent material and said organic binder.
