Abstract
A light-emitting device includes a thermally conductive substrate, a wiring electrode formed on the thermally conductive substrate, a resist formed on the wiring electrode except a terminal thereof, and a light-emitting element that is disposed in an element mounting region of the thermally conductive substrate and electrically connected to the terminal of the wiring electrode. A heat dissipation hole is formed in a region of the resist outside the element mounting region so as to expose a surface of the thermally conductive substrate.
