摘要:
A method for manufacturing a honeycomb structure, includes: a step of manufacturing a honeycomb formed body to manufacture a non-fired honeycomb formed body, the non-fired honeycomb formed body including a raw material composition containing a ceramic raw material and water; an induction drying step of drying the manufactured non-fired honeycomb formed body by induction drying to obtain a honeycomb dried body; and a firing step of firing the obtained honeycomb dried body to obtain a honeycomb structure. The induction drying step is to remove 10 to 50% of the entire water that the non-fired honeycomb formed body contained before drying by induction drying to obtain a first dried honeycomb formed body, then turn the first dried honeycomb formed body upside down and remove the residual water by further induction drying to obtain the honeycomb dried body.
