A light-emitting device with improved luminous efficiency is provided. A light-emitting device according to an embodiment includes a light-emitting element that emits excitation light of near-ultraviolet light or blue light, a yellow phosphor that is represented by formula (1), and converts the excitation light into yellow light, and a yellow phosphor. A first color conversion layer including a surrounding resin, having a volume concentration of a yellow phosphor of 7% or less, and having a cross-sectional area of a cross section parallel to the light emitting surface of the light emitting element larger than that of the light emitting surface. (Sr1-x1Cex1) a1AlSib1Oc1Nd1 (1) (In the formula (1), x1, a1, b1, c1, d1 satisfy the following relationship: 0 <x1≰0.1, 0.6 < a1 <0.95, 2.0 <b1 <3.9, 0 <c1 <0.45, 4.0 <d1 <5.0) [Selection] FIG. |
