Abstract: Provided is a light-emitting device that can reduce deterioration of characteristics of the light-emitting device by using a waterproof resin.
Solution
A light-emitting device includes a resin package including a lead, a resin member a light-emitting element, and a mold resin portion. The lead includes an exposed region exposed at the primary surface from the resin member. The light-emitting element is disposed in the exposed region of the lead. The mold resin portion includes a base portion having an upper surface positioned above a primary surface of the resin package and a lateral surface portion of the base portion covering a part of the lateral surface portion of the resin package and a lens portion that seal the light-emitting element. In a cross-sectional view, a first point is an outermost point of the upper surface of the base portion, the second point is an outermost point of the lateral surface portion of the base portion, and the light-emitting element is positioned closer to a back surface of the resin package than the first point and is positioned above the second point.
