Abstract: A method for manufacturing a light-emitting device includes: forming a cover, which comprises: sandwiching a fixing member by a molding device, injecting a light-transmissive material into a space defined in the molding device, and hardening or curing the injected light-transmissive material, wherein the formed cover comprises an upper portion, a sidewall, and a recess, the cover being integrated with the fixing member such that the fixing member projects from a part of an outer lateral surface of the sidewall; disposing a light-transmissive member on a light extraction surface of a light-emitting element to be disposed on a substrate; and disposing the cover so that the light-emitting element is housed in the recess. The fixing member is formed of a material that is deformable due to a pressing force generated in the event of an engagement with a counterpart member.

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.-

A surface area of a first surface of the optically functional part is greater than a surface area of a second surface of the optically functional part. The flange part defines at least one first recess in a surface located at a same side as the second surface.

Abstract: A light-emitting device includes: a substrate; a light-emitting element disposed on the substrate; a light-transmissive member disposed on a light extraction surface of the light-emitting element; a cover that covers the light-emitting element with a gap between the cover and the light-emitting element, the cover including: an upper portion that is transmissive to light emitted from the light-emitting element, a sidewall extending along a peripheral edge of the upper portion and having an outer lateral surface, and a recess defined by the upper portion and the sidewall; and a fixing member arranged on at least a part of the outer lateral surface of the sidewall of the cover. The fixing member is formed of a material that is deformable due to a pressing force generated in the event of an engagement with a counterpart member.
