Abstract
A method for drying a honeycomb formed body, the honeycomb formed body being an unfired honeycomb formed body including a raw material composition containing a ceramic raw material and water, the method including: a dielectric drying process of obtaining a primary dried honeycomb formed body from which 30 to 70% of entire moisture contained in the unfired honeycomb formed body before the drying is removed by performing dielectric drying on the unfired honeycomb formed body while maintaining a temperature of a central portion of the unfired honeycomb formed body at 100° C. or less; and a microwave drying process of obtaining a honeycomb dried body from which residual moisture is removed by performing microwave drying on the primary dried honeycomb formed body obtained in the dielectric drying process.
