Abstract: Provided is a light-emitting device having a light-emitting portion having a light-emitting element in a space surrounded by a support substrate, a metal substrate, and a sealing material, in which the sealing material is provided to surround the periphery of the light-emitting portion, the light-emitting element has a first electrode, a layer having a light-emitting organic compound, and a second electrode, the support substrate and the first electrode are each capable of transmitting light emitted from the light-emitting organic compound, and the space contains gas inert to the light-emitting element or is in a vacuum. The light-emitting device has, over the second electrode, a first high-emissivity layer that has higher emissivity than the second electrode and is thermally connected to the second electrode, and a low-reflectivity layer with which a metal substrate surface facing the support substrate is provided and which has lower reflectivity than the metal substrate.
