Abstract

A light source unit includes: a first light emission point from which a first beam is emitted; a second light emission point from which a second beam is emitted and which is disposed apart from the first light emission point in a second direction perpendicular to a first direction; a deflection element that deflects the first and/or second beam; and a first condensing optical element that focuses, on a light collection surface, the first and second beams. The first beam at the first light emission point overlaps the second beam at the second light emission point in a third direction, and on the light collection surface, the first and second beams overlap each other in the second direction and are separate from each other in the third direction.
