Abstract: A lamp (10) for a vehicle includes a light source unit (12) configured to emit light. The light source unit (12) includes a substrate (110) that includes a wiring electrode, a plurality of semiconductor light emitting devices (150) electrically connected to the wiring electrode, a plurality of phosphor layers (180) that respectively cover the plurality of semiconductor light emitting devices (150) and that are configured to convert wavelengths of light, and barrier ribs (160) disposed on the substrate (110) and configured to reflect light, the barrier ribs (160) being interposed between the plurality of semiconductor light emitting devices (150). A height of each of the barrier ribs (160) exceeds a height of each of the plurality of semiconductor light emitting devices (150) in a thickness direction of the plurality of semiconductor light emitting devices (150).
