Abstract
A method for manufacturing a honeycomb structure, includes: a step of manufacturing a honeycomb formed body to manufacture a non-fired honeycomb formed body having volume of 7 L or more; a drying step of drying the manufactured non-fired honeycomb formed body to obtain a honeycomb dried body; and a firing step of firing the obtained honeycomb dried body to obtain a honeycomb structure. The drying step includes: an induction drying step to obtain a first dried honeycomb formed body by removing 20 to 80% of the entire water that the non-fired honeycomb formed body contained before drying, and a microwave drying step to obtain a honeycomb dried body by removing the residual water. The honeycomb dried body subjected to this microwave drying step is obtained by removing 90% or more of the entire water that the non-fired honeycomb formed body contained before drying.
