Abstract: A light-emitting device includes a base structure, a light-emitting element, an optical member, and first and second adhesive parts. The first adhesive parts are disposed in first and second regions of a second surface of the base structure. The second adhesive parts are located at both opposite sides of the first adhesive part without being in contact with the first adhesive part. In the top view, a virtual first line segment, which connects two points respectively on the first adhesive parts in the first and second regions, extends across a first surface of the base structure. A virtual line segment, which connects two points respectively on the second adhesive parts at the both opposite sides of the first adhesive part, does not extend across the first surface. A width of the first adhesive part along the line segment is greater than a width of the second adhesive part.
