According to one embodiment, a light-emitting device includes a ceramic substrate (25), a plurality of light-emitting elements (28), and pressure member (33, 34, 71, 72). The substrate (25) includes a first surface (25a) in contact with a thermally radiative member (2), a second surface (25b) positioned in a side opposite to the first surface (25a), and an outer circumferential surface (25c) which bridges outer circumferential edges of the first surface (25a) and the second surface (25b). The light-emitting elements (28) are mounted on the second surface (25b) of the substrate (25). The pressure member (33, 34, 71, 72) elastically press the substrate (25) toward the thermally radiative member (2). A gap (g) is provided between the pressure member (33, 34, 71, 72) and the outer circumferential surface (25c) of the substrate (25). |
