A light-emitting device includes a package and a light-emitting element. The package includes a pair of leads each including a main body portion and an extension portion, a resin portion holding the pair of leads, and a concave portion having a bottom surface where an upper surface of each of the pair of leads is exposed. The extension portion extends from an outer edge of the main body portion to an outer surface of the package. The light-emitting element is mounted at the bottom surface of the concave portion. The main body portion has a trench and a through-hole in a portion of the main body portion buried in a sidewall of the concave portion. The through-hole is continuous with the trench. When viewed in top-view, the through-hole is provided inward of the outer edge of the main body portion at a vicinity of the extension portion.
