The present invention provides a method for producing a honeycomb structure using-an unfired recycled raw material (which may be a fired material in the case of SiC) recovered in the production process of a honeycomb structure, wherein the resulting honeycomb structure has low thermal expansion and porosity similar to those of honeycomb structures obtained using inherent starting raw materials and yield of the honeycomb structure can be improved and production cost can be considerably reduced, and further provides the honeycomb structure. That is, the present invention provides a method for producing a honeycomb structure using, as a part of a starting material, a recycled raw material recycled from a recovered material which is produced in the production process of the honeycomb structure and originates from the starting material for the honeycomb structure, and further provides the honeycomb structure. The recycled raw material is ground so that it has an average particle diameter of 10-2000 mum and contains 10% or less by weight of particles having an average particle diameter of 2800 mum or more.
