A reclaimed ceramic starting material is produced from scrap generated in a method for producing a cordierite ceramic body. The scrap is an unnecessary part generated in a cutting step of cutting a dried ceramic molded article into a predetermined length or a defective dried ceramic molded article generated in a drying step of drying an extruded ceramic material. The scrap is crushed. From a powder obtaind by crushing, at least particles smaller than the predetermined size are removed to produce a reclaimed powder having a particle size within a predetermined size range. The reclaimed powder is used as a reclaimed ceramic starting material. Instead of crushing, the scrap may be fired at a temperature where a contained binder can burn away to obtain a reclaimed powder. The reclaimed ceramic starting material ensures no deterioration in the quality of a cordierite ceramic body produced therefrom.
