1. A light-emitting device comprising:
a reflective structure having a first surface and a second surface and having, on the first surface, an opening whose side surface is provided with a first reflective film;
a semiconductor light-emitting element including a first conductivity-type layer, an active layer, and a second conductivity-type layer that are stacked, the opening of the reflective structure and the active layer being disposed to be opposed to each other; and
a support member having a light-transmitting property and having a first surface and a second surface, the semiconductor light-emitting element being disposed on the first surface side, the reflective structure being disposed on the second surface side, the second surface being at least partially in contact with the first surface of the reflective structure,
wherein the support member has unevenness on at least a portion of the second surface opposed to the reflective structure, and
wherein, in planar view, the active layer has a size smaller than a bottom of the opening of the reflective structure.
