A light-emitting device includes a support including a wall portion; a light-emitting element placed on the support and surrounded by the wall portion in a plan view; a first light-transmissive member having a first outer surface and a second outer surface, which is located above the first outer surface and is located inside the first outer surface in the plan view, and covering the light-emitting element and the wall portion; and a light-shielding member covering the first light-transmissive member. The first outer surface and the second outer surface are exposed from the light-shielding member, and a surface roughness of the first outer surface is rougher than a surface roughness of the second outer surface.
