A ceramic body for dental prosthesis which can suppress a variation in quality in the sole ceramic body for dental prosthesis due to expansion of its diameter, and can be manufactured easily, and a method for manufacturing the same are provided.The ceramic body for dental prosthesis is made of a ceramic material, is shaped to have a circular planar shape and a disklike 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 disklike external shape so as to prepare the ceramic body for dental prosthesis having a diameter of 50 mm or more.
