ILLUMINATION UNIT

An illumination unit includes: a substrate to which a first light-emitting element is mounted; a housing that holds the substrate; a case that is attached to the housing so as to cover the substrate and can output light of the first light-emitting element to the outside; and a light-blocking cover that is attached to the substrate, is provided so as not to cover the first light-emitting element in a direction in which light is output while surrounding the first light-emitting element, and is formed higher from a front face of the substrate than the first light-emitting element.
