CERAMIC COMPLEX, LIGHT SOURCE FOR PROJECTOR, AND METHOD FOR PRODUCING CERAMIC COMPLEX
Provided are a ceramic complex capable of improving the luminous efficiency, a projector comprising a ceramic complex, and a method for producing a ceramic complex. Proposed is a ceramic complex including a rare earth aluminate fluorescent material having an average particle diameter in a range of 15 m or more and 40 μm or less, aluminum oxide having a purity of aluminum oxide of 99.0% by mass or more, and voids, wherein the content of the rare earth aluminate fluorescent material is in a range of 15% by mass or more and 50% by mass or less relative to a total amount of the rare earth aluminate fluorescent material and the aluminum oxide, and a void fraction is in a range of 1% or more and 10% or less.
