Patent ID: 8323557

Claim:
A method for manufacturing a honeycomb structure, comprising: molding a ceramic raw material to manufacture at least one honeycomb molded body having a plurality of cell walls extending along a longitudinal direction of the at least one honeycomb molded body to define cells; filling first cells at first end portions provided at a first end face side of the at least one honeycomb molded body in the longitudinal direction with a first plug material paste to form first plugs; filling third cells at third end portions provided at a third end face side of the at least one honeycomb molded body in the longitudinal direction with a third plug material paste to form first plugs; firing said at least one honeycomb molded body to manufacture at least one honeycomb fired body having first plugs; cutting said at least one honeycomb fired body along a plane substantially perpendicular to the longitudinal direction to create a second end face side of the at least one honeycomb fired body; filling second end portions of second cells provided at the second end face side in the longitudinal direction with a second plug material paste, the second cells having none of the first plugs, the second plug material being different than the first plug material paste and the third plug material paste; solidifying the plug material paste in the second end portions through heating to form second plugs; and producing a honeycomb block including at least one honeycomb fired body.
