Abstract
In a light-emitting device substrate (), a light reflecting surface covered with an anodized aluminum layer () is formed on one side of a base (), and a glass-based insulator layer () and electrode patterns () disposed on the first insulating layer () are formed on the one side of the base () in a region not covered with the anodized aluminum layer (). A glass-based insulator layer () is formed at least on the other side of the base () that is opposite the one side of the base (). Therefore, a light-emitting device substrate having high reflectivity, high heat dissipation capability, dielectric withstand capability, and long-term reliability and excellent in mass productivity can be realized.
