PROBLEM TO BE SOLVED: To provide a partition which miniaturizes a lighting unit provided in a panel section, and which illuminates the whole usage areas on both sides, partitioned with the panel section, at sufficient brightness. SOLUTION: In this partition, the lighting unit is installed along an upper end of the panel section. The lighting unit includes a linear light source in which a plurality of LED elements are mounted in the state of being juxtaposed on a substrate, a base which has a top surface opened and inside which the linear light source is housed from the opening, and a reflector which is arranged on an optical path of an outgoing beam from the linear light source. The reflector comprises first and second reflecting surfaces. The first and second reflecting surfaces meet each other in a position above the central axis line of the linear light source; and a distance from a plane including the light-emitting surface of the LED element is increased as the first and second reflecting surfaces get away from a meeting portion. A one-side area across the panel section is illuminated with the beam reflected on the first reflecting surface, among the beams emitted from the LED element; and the other-side area across the panel section is illuminated with the beam reflected on the second reflecting surface.
