Zusammenfassung:A ceramic complex that has improved optical characteristics including luminous efficiency is provided. A method for producing a ceramic complex, including: preparing a molded body containing rare earth aluminum garnet fluorescent material, aluminum oxide, and lutetium oxide, and having a content of the rare earth aluminum garnet fluorescent material in a range of 15% by mass or more and 50% by mass or less, and a content of the lutetium oxide in a range of 0.2% by mass or more and 4.5% by mass or less, based on the total amount of the rare earth aluminum garnet fluorescent material, the aluminum oxide, and the lutetium oxide; and calcining the molded body in an air atmosphere to provide a ceramic complex having a relative density in a range of 90% or more and less than 100%.
