Abstract
A light source unit includes light-emitting elements, a light-shielding body, and a rod lens including a first end surface, a second end surface, and a side surface. The light-shielding body is separated from the side surface, covers the side surface, includes an opening exposing at least a portion of the second end surface, and includes a tip protruding further than the second end surface in a first direction from the first end surface toward the second end surface. A first plane crosses the first direction and is at the same first-direction position as the tip. A second plane crosses the first direction and is at the same position as the second end surface or between the tip and second end surface in the first direction. A first surface area of the opening at the first plane is greater than a second surface area of the opening at the second plane.
