LIGHT-EMITTING DEVICE, ILLUMINATION DEVICE, AND METHOD FOR MANUFACTURING LIGHT-EMITTING DEVICE

摘要

A light-emitting device (50) includes a light-emitting element (60), a ceramic substrate (70) having an installation surface (70a) on which the light-emitting element (60) is installed and a non-installation surface (70b) on the reverse of the installation surface (70a) on which the light-emitting element (60) is not installed, and a metal reflective film (90) formed on the non-installation surface (70b). The metal reflective film (90) reflects the light from the light-emitting element (60), which passed through the ceramic substrate (70).
