Abstract:
1. A method for manufacturing a honeycomb structured body comprising: molding ceramic raw material to form a pillar-shaped honeycomb molded body having a multiplicity of cells disposed in parallel with one another in the longitudinal direction with a cell wall therebetween, filling in either one of the end portions of each of said cells with a plug material paste, drying a plug material paste layer by simultaneously blowing hot air onto both end faces of said honeycomb molded body from a plurality of hot air blow ports of a hot air drying apparatus, wherein the hot air drying apparatus comprises, inside a drying oven, said hot air blow ports positioned on opposite sides of said honeycomb molded body and disposed at locations facing an end face of said honeycomb molded body in order to preferentially dry both end portions of the plug material paste layer, and firing this honeycomb molded body to manufacture a honeycomb structured body comprising a honeycomb fired body.
