摘要: A planar light source device (1) is provided with a light source unit (4B) wherein a semiconductor light-emitting element (43) is covered with a transparent resin part (44); a light guide body (3) having a side surface (3B) facing the light source unit (4B); and a holding body (5B), which has the light source unit (4B) fixed on one side and the light guide body (3) on the other side, and a space between a transparent resin part (44) and the side surface (3B), and connects the light source unit (4B) and the light body (3). The light source unit (4B) moves with extension and retraction of the light guide body (3). The holding body (5B) holds a distance constant between the transparent resin part (44) of the light source unit (4B) and the side surface (3B) of the light guide body (3) to extension and retraction of the light guide body (3).
