Abstract
A light-emitting device includes: a base member including: a first lead, a second lead, and a securing member securing the first and second leads; a light-emitting element mounted on an upper surface of the base member; a frame, a part of which is disposed on the upper surface of the base member to surround the light-emitting element; a first member covering at least a portion of an upper surface of the securing member that is exposed at an outer peripheral side of the frame in a top view, the first member being arranged intermittently under the frame and containing a reflective material; and a second member covering the light-emitting element, the frame, and the first member. The frame has a first region on which the first member is arranged and a second region on which the first member is not arranged, the first and second regions having different heights.
