Abstract: Provided is a light-emitting device on which a plurality of light-emitting elements connected in series are mounted at high density. The light-emitting device has: a first support body; a plurality of light-emitting elements; and a plurality of second support bodies which each support at least one light-emitting element among the plurality of light-emitting elements and are disposed on the first support body in a state of being aligned in a first direction. In regions at both ends in a second direction intersecting with the first direction when viewed from the top, each of the plurality of second support bodies has provided, in a region at one end, a first wiring layer for connecting to a first electrode of the corresponding light-emitting element, and has provided, in a region at the other end, a second wiring layer for connecting to a second electrode of the corresponding light-emitting element. The first wiring layer has: a first connection region connected to the first electrode of the corresponding light-emitting element; and a first end region not connected to the light-emitting element and closer to said one end than the first connection region. The second wiring layer has: a second connection region connected to the second electrode of the corresponding light-emitting element; and a second end region not connected to the light- emitting element and closer to the other end than the second connection region. Between the second support bodies adjacent to each other in the first direction among the plurality of the second support bodies, the positions of the first end regions and the positions of the second end regions are reversed in the second direction.
