Abstract
A first light source and a second light source are arranged so that a protrusion direction of a first terminal from a first supporting body and a protrusion direction of a second terminal from a second supporting body are different when viewed in the longitudinal direction of a light guide. The first light source and the second light source are arranged so as to reduce a protrusion direction of the first supporting body and the second supporting body in a predetermined direction from an area where the first light source and the second light source overlap when viewed in the longitudinal direction of the light guide.
