| 主权项 | 1. A ceramics composite comprising: a fired body comprising: a matrix phase comprising Al2O3 or a substance in which one selected from Sc2O3 and Ga2O3 is incorporated into Al2O3;a main phosphor phase formed in the matrix phase and comprising a substance represented by a general formula A3B5O12:Ce in which A is at least one selected from Y, Gd, Tb, Yb and Lu, and B is at least one selected from Al, Ga and Sc; anda CeAl11O18 phase mixed in the matrix phase and the main phosphor phase, wherein the main phosphor phase is included in an amount of 20% by volume to 25% by volume in a total volume of the ceramics composite, and wherein the CeAl11O18 phase is included in an amount of 0.5% by volume to 5.0% by volume in a total volume of the ceramics composite. | ||
