Abstract
To provide a glass ceramic body wherein the deterioration of the reflectance due to black coloration is suppressed, and the unevenness of the firing shrinkage is suppressed. A glass ceramic body comprising a glass matrix and alumina particles dispersed therein, wherein the glass matrix is not crystallized, a ceramic part composed of the dispersed alumina particles has an α-alumina crystal structure and a crystal structure other than the α-alumina crystal structure.
