PROBLEM TO BE SOLVED: To provide a production method of a cordierite ceramic body having a coefficient of thermal expansion similar to the one obtained by using the original starting raw material without necessitating strict control of pulverizing conditions while keeping a good yield of a regenerated raw material when producing the cordierite ceramic body using the unburned regenerated raw material recovered in the production process of the cordierite ceramic body. SOLUTION: At least a part of a binder is removed from the regenerated raw material which is recovered in the production process of the cordierite ceramic body and comprises a prescribed formulation for cordierite raw material. The cordierite ceramic body is produced by pulverizing the regenerated raw material thus obtained to prepare pulverized powder, adding water, a binder, etc., to the pulverized powder, kneading it to prepare regenerated body, compacting the prepared body and firing it. |
