摘要：
[Problem] A ceramic substrate for mounting a luminescent element which has high reflectivity of 90% or above in ultraviolet to infrared regions (350 nm to 1,000 nm) and which has satisfactory mechanical properties. [Solution] A ceramic substrate (1) for mounting a luminescent element includes a content of aluminum oxide of from 94 mass% to 97 mass%, silicon oxide, and at least one of calcium oxide and magnesium oxide. The ceramic substrate (1) has a porosity of from 2.5% to 4.5%, a number of pores of from 7,000 to 11,000, and a cumulative relative frequency of 70% or above in an equivalent circle diameter of 1.6 µm or less in a pore distribution, when viewing pores having an equivalent circle diameter of 0.8 µm or more in a surface area portion of 9.074×10 5 µm 2 of a surface (1a) of the substrate (1). The ceramic substrate (1) has high reflectivity of 90% or above in ultraviolet to infrared regions and has satisfactory mechanical properties, which is suitable for use in a luminescent device (21).
