Abstract: A light-emitting device includes a substrate comprising a base member, a first wiring, a second wiring, and a via hole; at least one light-emitting element electrically connected to and disposed on the first wiring; and a covering member having light reflectivity and covering a lateral surface of the light-emitting element and a front surface of the substrate. The base member defines a plurality of depressed portions separated from the via hole in a front view and opening on a back surface and a bottom surface of the base member. The substrate includes a third wiring covering at least one of inner walls of the plurality of depressed portions and electrically connected to the second wiring. A depth of each of the plurality of depressed portions defined from the back surface toward the front surface is larger on a bottom surface side than on an upper surface side of the base member.

Abstract: A light emitting device includes a resin molding, first and second leads, and a light emitting element. The resin molding includes a front surface defining an opening, and a lower surface adjacent to the front surface. The first and second leads each includes an outer lead portion and an inner lead portion. The outer lead portion protrudes from the lower surface of the resin molding, and includes a bent portion bent along the lower surface. A surface on an inner side of the bent portion including a first recessed section. The inner lead portion includes an embedded portion embedded in the resin molding, and an exposed portion exposed in the opening. A surface of the embedded portion opposite from the surface where the first recessed section is provided includes a second recessed with a part of the resin molding being positioned in the second recessed section.

Abstract: A light-emitting device includes, a substrate, a plurality of light-emitting elements aligned along a longitudinal direction, and a covering member. The substrate includes a pair of first depressed portions and a second depressed portion each opening on a back surface and a bottom surface of a base and positioned on both end sides of the base in the longitudinal direction. The second depressed portion has a width larger than a width of the first depressed portions as measured along a height direction. First metal films extend from inside the first depressed portions to the back surface. A second metal film extends from inside the second depressed portion to the back surface. A solder mask covers at least a part of each of the first metal films and at least a part of the second metal film on the back surface of the base.
