Disclosed is a method for manufacturing a ceramic molded part that can be easily removed from a mold while preventing breakage of the ceramic molded part, etc., and can be densified more uniformly, and the mold and ceramic used therefor Provide parts. A lower mold body 3 and an upper mold body 9 of a molding die 1 are provided with a lower outer peripheral restraining portion 15 and an upper outer peripheral restraining portion 16 for molding an outer peripheral portion of a lens, and an optically mirror-finished optical device. A molding surface 3a and an optical molding surface 9a are respectively formed. The upper outer periphery restraint portion 16 and the lower outer periphery restraint portion 15 are formed to have predetermined thicknesses α1 and α2 in the pressure axis direction, respectively. Between the lower mold main body 3 and the upper mold main body 9, there is provided an outer peripheral unconstrained portion 17 that does not restrain the ceramic when the ceramic material is molded.
