Summary:A linear light-concentrating device includes: a light-emitting body having light-emitting surfaces; a first optical element group; a second optical element group having apertures; and a light-transmitting columnar member. The first optical element group is divided into first optical elements each having a deflecting characteristic that causes an incident beam to be converted to an exit beam deflected in a first direction. The second optical element group is divided into second optical elements. The first optical elements include constituent units each including at least two of the first optical elements, and the deflecting characteristics of the first optical elements are such that a group of exit beams from each of the constituent units is deflected toward a corresponding one of the apertures of the second optical element group. The optical axes of the second optical elements are decentered toward the optical axis of the columnar member.
