An emission surface (123) of the lens (120) includes a non-parallel light emission region where light emitted from the first light source (111A) is emitted as light that is not parallel to the optical axis of the first light source (111A), and light emitted from the second light source (111B) is emitted as light that is not parallel to the optical axis of the second light source (111B). The non-parallel light emission region is located near a boundary section (B) between the first region (121A) and the second region (121B).
