Abstract
A lighting device including a light-emitter including light emitting elements, and a support having a first surface that carries a wiring line electrically connecting element electrodes of the light emitting elements and a light emitting surface, and a substrate including a base substrate, a conductor formed on a first surface of the base substrate, an adhesive member formed on a second surface of the base substrate, and a through-hole penetrating the substrate. A space is formed between the substrate and the light-emitter to communicate with a bottomed hole formed in a location of the through-hole as a result of adhering an adhesive surface of the adhesive member to a surface of the light-emitter having the wiring line formed thereon. The wiring line is connected to the conductor via a filler filling the bottomed hole, and the space is located outside an opening of the bottomed hole.
