Abstract:
1. A light-emitting device comprising: a substrate including an upper surface, a lower surface opposite to the upper surface, a peripheral side surface extending between peripheral edges of the upper surface and peripheral edges of the lower surface, a pair of electrodes as a first electrode and a second electrode that are disposed on the upper surface of the substrate; and a light-emitting element including a pair of element electrodes as a first element electrode and a second element electrode and disposed on the second electrode of the substrate; a pair of wires as a first wire and a second wire, the first wire electrically connecting the first electrode of the substrate and the first element electrode of the light-emitting element, and the second wire electrically connecting the second electrode of the substrate and the second element electrode of the light-emitting element; a first through-hole in a shape that is a quarter of circle disposed at a first corner of the substrate and electrically connected to the first electrode of the substrate; a second through-hole in a shape that is quarter of circle disposed at a second corner that is diagonally opposite to the first corner of the substrate and electrically connected to the second electrode of the substrate; a first cover in a shape that is a quarter of circle disposed on the upper surface of the substrate and covering the first through-hole at the first corner of the substrate; and a second cover in a shape that is a quarter of circle disposed on the upper surface of the substrate and covering the second through-hole at the second corner of the substrate.
