A ceramic body for dental prosthesis can suppress a variation in quality in the sole ceramic body for dental prosthesis due to expansion of its diameter. The ceramic body for dental prosthesis is made of a ceramic material, is shaped to have a circular planar shape and a disk-like external shape, and has a diameter of 50 mm or more. The method for manufacturing this ceramic body for dental prosthesis includes: preparing a ceramic material； shaping the ceramic material by press shaping or by a machine tool； temporarily sintering the ceramic material at a temperature from a sintering temperature that provides theoretical density −；700° C. or more to the sintering temperature −；100° C. or less； and shaping the ceramic material to have a circular planar shape and a disk-like external shape so as to prepare the ceramic body for dental prosthesis having a diameter of 50 mm or more.
