Abstract
According to one embodiment, a light-emitting device includes a ceramic substrate, a plurality of light-emitting elements, and pressure member. The substrate includes a first surface in contact with a thermally radiative member, a second surface positioned in a side opposite to the first surface, and an outer circumferential surface which bridges outer circumferential edges of the first surface and the second surface. The light-emitting elements are mounted on the second surface of the substrate. The pressure member elastically press the substrate toward the thermally radiative member. A gap is provided between the pressure member and the outer circumferential surface of the substrate.
