Abstract: A process for producing a honeycomb structure includes: manufacturing a honeycomb-shaped formed article (honeycomb formed article) by kneading a forming raw material containing ceramic as a main component and a forming auxiliary, an additive, and a pore former to prepare kneaded clay and forming and drying the kneaded clay, calcining the honeycomb formed article to obtain a calcined article, and firing the calcined article. Upon performing a tensile load measurement of the kneaded clay or the formed article, a slope θ of the straight line through an inflection point b and an yielding point c of a graph showing a relation between the tensile load and a displacement amount is below 100% of a slope δ of the straight line through a starting point a where an elastic deformation is shown and the inflection point b. According to the present invention, there can be produced a honeycomb structure capable of suppressing defect generation upon forming a honeycomb to improve yield, hardly generating a new defect upon actual use of the honeycomb structure, and having excellent durability.
